Meteorite fragments recovered in Germany after fireball seen over northwestern Europe.

More than 3000 witnesses in Belgium, France, Germany, Luxembourg, and the Netherlands have reported observing a bright fireball meteor at about 6.55 pm local time (about 5.55 pm GMT) on Sunday 8 March 2026, with some witnesses also reporting a sonic boom. The meteor is described as having moved from southwest to northeast for about six seconds before exploding in a fireball over the German state of Rhineland-Palatinate. A fireball is defined as a meteor (shooting star) brighter than the planet Venus. 

A very bright fireball moving from the southwest to the northeast was observed by many people in Belgium, France, Germany, Luxembourg, and the Netherlands. Bernd Klemt/AllSky7 fireball network/European Space Agency.

Objects of this size probably enter the Earth's atmosphere several times a year, though unless they do so over populated areas they are unlikely to be noticed. They are officially described as fireballs if they produce a light brighter than the planet Venus. The brightness of a meteor is caused by friction with the Earth's atmosphere, which is typically far greater than that caused by simple falling, due to the initial trajectory of the object. Such objects typically eventually explode in an airburst called by the friction, causing them to vanish as a luminous object. However, this is not the end of the story as such explosions result in the production of a number of smaller objects, which fall to the ground under the influence of gravity (which does not cause the luminescence associated with friction-induced heating).

These 'dark objects' do not continue along the path of the original bolide, but neither do they fall directly to the ground, but rather follow a course determined by the atmospheric currents (winds) through which the objects pass. Scientists are able to calculate potential trajectories for hypothetical dark objects derived from meteors using data from weather monitoring services.

Shortly after the meteor was sighted, two residents of a flat in the German city of Koblenz reported an impact which had caused a football-sized hole in their roof, as well as damage to a tiled floor in the room underneath. A search of the flat yielded eleven fragments of rock with masses of between 6 and 161 g. A number of smaller fragments were subsequently found in a neighbouring courtyard by professional meteorite-hunters and sold. Police in Koblenz have subsequently issued a warning to other meteorite-hunters in the area to respect private property, and not to collect suspected fragments from areas which they have not been given permission to enter.

The meteorite fragments have a pale interior and a near-black crust, making it likely that they are a type of stoney meteorite called a HED (howardite–eucrite–diogenite) achondrite breccia. These meteorites resemble terrestrial igneous rocks, and are therefore presumed to have come from a body large enough for magma differentiation and igneous processing to have occurred. HED meteorites comprise about 5% of all meteorites recovered on Earth, and about 60% of achondritic meteorites (meteorites which do not contain chondrules, spherules of glassy material thought to have formed from molten droplets in space before being incorporated into larger bodies).

While HED meteorites vary somewhat in composition, all are thought to derive from the surface of the Asteroid 4 Vesta. Studies of these meteorites have produced crystallisation ages of between 4.43 and 4.55 billion years, and all show signs of having formed in an environment where igneous differentiation has occurred. These meteorites are thought to have been dislodged from the surface of their parent body by ancient impacts.

Asteroid 2026 EM passes the Earth.

Asteroid 2026 EM passed by the Earth at a distance of about 28 424 km (7% of the average distance between the Earth and the Moon, or 0.02% of the distance between the Earth and the Sun, but 71 times the distance at which the International Space Station orbits the Earth), at about 7.45 pm GMT on Monday 7 March 2026. There was no danger of the asteroid hitting us, though were it to do so it would not have presented a significant threat. Asteroid 2026 EM has an estimated equivalent diameter of 1-3 m (i.e. it is estimated that a spherical object with the same volume would be 1-3 m in diameter), and an object of this size would be expected to explode in an airburst (an explosion caused by superheating from friction with the Earth's atmosphere, which is greater than that caused by simply falling, due to the orbital momentum of the asteroid) more than 42 km above the ground, with only fragmentary material (if that) reaching the Earth's surface.

2026 EM was discovered on 6 March 2026 (the day of its closest approach to the Earth) by the University of Szeged's Szeged Asteroid Program, which is located at the Piszkéstető Mountain Station in the Mátra Mountains to the northeast of Budapest. The designation 2022 EM implies that it was the 12th asteroid (object M - in numbering asteroids the letters A-Y, excluding I, are assigned numbers from 1 to 25, with a number added to the end each time the alphabet is ended so that A = 1, A1 = 26, A2 = 51, etc., which means that M implies the 12th asteroid) discovered in the first half of March 2026 (period 2026 E - the year being split into 24 half-months represented by the letters A-Y, with I being excluded).

2026 EM has a 425 day (1.16 year) orbital period, with an elliptical orbit tilted at an angle of 4.77° to the plain of the Solar System which takes in to 0.89 AU from the Sun (89% of the distance at which the Earth orbits the Sun) and out to 1.32 AU (132% of the distance at which the Earth orbits the Sun). It is therefore classed as an Apollo Group Asteroid (an asteroid that is on average further from the Sun than the Earth, but which does get closer). This means that Asteroid 2026 EM has occasional close encounters with the Earth, with the most recent having happened in March 2019, and the next predicted for March 2039. The asteroid also has occasional close encounters with the planet Mars, with the next such encounter predicted for May 2032.

Chile officially recognised as the first country in the Americas to have eliminated Leprosy.

Chile has become the first country in the Americas to be recognised to have officially eliminated Leprosy, according to a press release issued by the World Health Organization on 4 March 2024. Chile is only the second country globally to reach this goal, following Jordan in September 2024. The conformation also makes Chile the sixth country in the Americas to have eliminated at least one Neglected Tropical Disease, joining Brazil, Colombia, Ecuador, Guatemala, and Mexico.

Leprosy was first recorded in Chile on Rapa Nui (Easter Island) in the late nineteenth century, with some subsequent cases reported on the mainland. The last reported case of a person becoming infected with the disease on Chilean territory occurred on Rapa Nui in 1993. However, the country has continued widespread monitoring for Leprosy, with 47 cases reported between 2012 and 2023, all of which were acquired outside of the country, and all of which were successfully treated.

Leprosy is caused by the Bacteria Mycobacterium leprae and Mycobacterium lepromatosis. It is essentially a skin disease, with the Bacteria infecting patches of skin, which can become dry and itchy, lose their pigmentation, suffer skin thickening, nerve damage, and local immune system failure, which can cause the patches vulnerable to secondary infections by other Bacteria, Fungi, and Viruses. It is these secondary infections which cause the ulceration and tissue loss associated with the disease, which can lead to shortening or loss of fingers and toes, or even facial features. The nerve damage associated with the disease can cause patients to fail to notice wounds, making them more vulnerable to infection.

Leprosy is thought to be spread by mucus droplets exposed by through the mouth or nose (which can enable it to spread among children rapidly) but not through most other forms of contact; it is not sexually transmitted, and patients with HIV do not appear to be any more vulnerable, although malnutrition may be a factor. Much of the Human population appear to be naturally immune to Leprosy, with vulnerability to the disease being genetic, and tending to run in families, which can be problematic, particularly in poorer communities where people are living in cramped conditions and have trouble accessing medicine. 

Leprosy is a zoonotic disease, with wild reserves of the Bacteria found in a number of Animal species, including Primates such as the Chimpanzee, the Sooty Mangabey, and the Cynomolgus Macaque. In Europe is thought to have been spread by Red Squirrels, which are known to be vulnerable to the disease, and which were extensively hunted for their fur in the Middle Ages. The disease is thought to have been introduced to the Americas by European settlers, but has become established in there in Armadillos, which can act as a wild vector, spreading Leprosy back to Humans.

The first effective treatment for Leprosy was developed by Alice Augusta Ball, a young researcher at the College of Hawai'i (now the University of Hawai'i), in 1915 (Ball is also noted to have been the first African American woman to achieve a masters degree in chemistry, the first African American woman hired as a chemistry instructor at the College of Hawai'i, and possibly the first African American woman to publish an article in a major scientific journal). Today it is typically treated with a combination of antibiotics such as rifampicin, dapsone, and clofazimine, with other antibiotics available if resistance to these is encountered. Such treatments can typically eliminate the disease completely, although the courses of treatment are long (6-12 months) and involves taking multiple pills each day, which can be problematic, particularly in younger children.

Leprosy is still considered to be endemic to 132 countries, with around 200 000 new cases reported each year. The worst affected countries are Brazil, India, and Indonesia, each of which typically reports more than 10 000 new cases each year. Twelve other countries, Bangladesh, Democratic Republic of the Congo, Ethiopia, Madagascar, Mozambique, Myanmar, Nepal, Nigeria, Philippines, Somalia, Sri Lanka and Tanzania, typically report between 1000  and 10 000 new cases per year, while another 117 countries typically report between 1 and 1000 cases per year. The World Health Organization is currently working towards the global elimination of Leprosy in partnership with the Swiss drug company Novartis, which provides multi-drug therapy for the disease to patients anywhere in the world at no cost, under the Partnership to Eliminate Leprosy scheme.

South African diamond mining company files for bankruptcy after five miners killed in flood.

South African mining company Ekapa Minerals has filed for liquidation following the death of five miners at its Ekapa Joint Shaft Mine at Kimberly in Northern Cape Province, South Africa, on 17 February 2026. The miners have been missing presumed dead since a slurry of water and mud rapidly filled the section of the mine where they were working. The area where the incident occurred was located 890 m below ground, and had only recently been opened up, and life support systems had been installed, but the sudden nature of the flood has led the mine operators to conclude that the incident was not survivable, and, following several days of attempts to reach and clear the site, that there is little hope of recovering the bodies of the lost miners.

Floods and inrushes typically occur when miners accidentally break through into pockets of water and gas trapped within rocks. Since such buried waters are often under high pressure due to the weight of rocks above them, they tend to escape into the mine rapidly, and on occasion explosively, leading to a highly dangerous situation in which miners are often rapidly overwhelmed. Such inrushes can also occur when miners encounter flooded disused mineworkings, a danger in areas where mining has occurred for a long time but good records have not been kept. The Ekapa mine had a history of flood inrush events, and the company had been warned by a parliamentary committee in 2025 that steps needed to be taken to avoid future events of this kind.

The closure of the mine is predicted to result in the loss of about 1200 jobs, a crisis for the city of Kimberly, which has a population of just under 97 000 people, and is already suffering from high unemployment rates due to the decline of the diamond industry. Furthermore, workers from the site report that they have not received their salaries for the month of February 2026, placing many of the in a very difficult situation financially. 

Ekapa Minerals purchased the Joint Shaft Mine from mining giant De Beers in 2016, and at the time of closure it was the last surviving diamond mine in Kimberly. In theory, the site could be sold on to another mining company following the liquidation process, but it is unclear if a buyer will be found given the mine's problems and a fluctuating diamond market.

Kimberly was founded in the 1870s following the discovery of diamonds in the area, and rapidly became a centre of wealth in the Cape Colony, opening South Africa's first stock exchange in 1881, and becoming the second city in the world to install electric street lighting the following year. However, in recent years the city's mines have closed one-by-one as the industry has become less viable. The long history of mining in the area means that there are no diamonds left close to the surface, and while they can still be found at greater depths, these are generally fairly small, making it hard for these mines to compete with either shallow, open pit mines elsewhere, or artificial lab-grown diamonds.

Denmark officially recognised as having ended mother-to-child transmission of HIV and Syphilis.

Denmark has been officially recognised as having eliminated mother-to-child transmission of HIV and Syphilis according to a press release issued by the World Health Organization on 27 February 2026. In doing so it becomes the first member of the European Union and the third European country to achieve this status (behind Moldova and Belarus, both of which were confirmed as having ended mother-to-child transmission of both diseases in 2016).

The World Health Organization is aiming for all countries to achieve the triple elimination of mother-to-child transmission of three critical diseases, HIV, Syphilis, and Hepatitis B, although to date only a single country has passed this milestone, the Maldives in October 2025. Denmark's progress makes it one of 23 countries to have ended mother-to-child transmission of at least one of these diseases, alongside Anguilla, Antigua and Barbuda, Armenia, Belarus, Belize, Bermuda, Brazil, Botswana, Cayman Islands, Cuba, Dominica, Jamaica, Malaysia, Maldives, Montserrat, Namibia, Oman, Republic of Moldova, Saint Vincent and the Grenadines, Sri Lanka, St. Kitts and Nevis, and Thailand.

The confirmation of Denmark's status comes following assessments by the World Health Organization's Regional Validation Committee for Europe, and Global Validation Advisory Committee in 2025. In order to be confirmed, it was necessary to demonstrate that 95% of all pregnant women in Denmark were tested for the diseases, and that new infant infections were below 50 in 100 0000 births. Denmark currently has 5950 people living with HIV, with less than 0.1% of pregnant women affected. It is possible to completely suppress the disease with antiretroviral treatments, preventing development of symptoms and all forms of transmission, including mother-to-child. In 2024, Denmark reported 626 cases of Syphilis, 524 in men and 102 in women; infections with this disease can be eliminated with antibiotics. Denmark is still working towards ending mother-to-child transmission of Hepatitis B.

Human Immunodeficiency Virus, or HIV, is a form of Lentivirus which causes infections in Humans, spread through sexual intercourse or exchange of blood. Notably, the Virus infects the cells of the Human immune system, where it is hard for that immune system to attack, and eventually leads to a breakdown of the immune system known as AIDS (Acquired Immune Deficiency Syndrome), during which the body becomes vulnerable to a wide range of infections, including many by micro-organisms which are not usually pathogenic. 

Untreated, HIV invariably leads to AIDS, and AIDS is invariably fatal, but, as with Syphilis, HIV infections can go through long phases of dormancy, leaving infected people unaware that they have the disease. Neither an effective vaccine nor a cure for HIV has yet been developed, however, it is possible to suppress the infection with a combination of anti-viral drugs, allowing patients to lead relatively normal lives, as long as their supply of antivirals is not interrupted. Children born to mothers with HIV are not automatically infected, as the Virus is usually unable to cross the placenta, but there is a high chance of infection during birth if the mother is not receiving treatment.

Syphilis is a sexually transmitted disease caused by the Spirochaete Bacterium Treponema pallidum. The symptoms of Syphilis can be variable, and it can go through long periods of dormancy, making the disease difficult to diagnose without modern testing methods. Syphilis infection in pregnant women leads to a raised risk of miscarriage, and infants born with the disease are prone to physical deformities, damage to the liver and spleen, and neurological problems. Syphilis can be treated with a range of antibiotics, including penicillin, although the development of a vaccine has proved difficult.
