    To date, nearly 28,000 near-Earth asteroids (NEAs) have been found by survey telescopes that continually scan the night sky, adding new discoveries at a rate of about 3,000 per year. But as larger and more advanced survey telescopes turbocharge the search over the next few years, a rapid uptick in ...

    The International Asteroid Warning Network (IAWN) will conduct an observational campaign in November with the goal of assessing the accuracy of the observation times reported by asteroid observers.

    On Aug. 14, 2021, a small near-Earth asteroid (NEA) designated 2021 PJ1 passed our planet at a distance of over 1 million miles (about 1.7 million kilometers). Between 65 and 100 feet (20 and 30 meters) wide, the recently discovered asteroid wasn’t a threat to Earth. But this asteroid’s approach ...

    In a study released Wednesday, NASA researchers used precision-tracking data from the agency's Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft to better understand movements of the potentially hazardous asteroid Bennu through the year 2300, significantly reducing uncertainties related to its future orbit, and improving scientists' ability to determine ...

    After its discovery in 2004, asteroid 99942 Apophis had been identified as one of the most hazardous asteroids that could impact Earth. But that impact assessment changed as astronomers tracked Apophis and its orbit became better determined.Now, the results from a new radar observation campaign combined with precise orbit analysis ...

    The largest asteroid predicted to pass by our planet in 2021 will be at its closest on March 21, providing astronomers a rare opportunity to get a good look at a rocky relic that formed at the dawn of our solar system.Called 2001 FO32, the near-Earth asteroid will make its ...

    Earth has captured a tiny object from its orbit around the Sun and will keep it as a temporary satellite for a few months before it escapes back to a solar orbit. But the object is likely not an asteroid; it's probably the Centaur upper stage rocket booster that helped ...
  • 2020-09-22
    A small near-Earth asteroid (or NEA) will briefly visit Earth's neighborhood on Thursday, Sept. 24, zooming past at a distance of about 13,000 miles (22,000 kilometers) above our planet's surface. The asteroid will make its close approach below the ring of geostationary satellites orbiting about 22,000 miles (36,000 kilometers) away ...

    Near Earth Asteroids, or NEAs, pass by our home planet all the time. But an SUV-size asteroid set the record this past weekend for coming closer to Earth than any other known NEA: It passed 1,830 miles (2,950 kilometers) above the southern Indian Ocean on Sunday, Aug. 16 at 12:08 ...

    A large near-Earth asteroid will safely pass by our planet on Wednesday morning, providing astronomers with an exceptional opportunity to study the 2-kilometer-wide (1.5-mile-wide) object in great detail.

    The annual Quadrantid meteor shower peaks on the night of 3/4 January and, as one of the recognised major meteor showers of the year, there’s a great chance to see at least dozens of shooting stars each hour, especially as the Moon will not interfere this year.

    In this series we are exploring the weird and wonderful world of astronomy jargon! You’ll be struck by today’s topic: bolide! It’s a bird! It’s a plane! It’s a…bolide? The word “bolide” has two main definitions, and even then it’s never used in a consistent way. The International Astronomical Union, for ...

    In this series we are exploring the weird and wonderful world of astronomy jargon! You’ll be surrounded by today’s topic: coma! “Coma” comes from the Greek word for “hair”, and it’s also the origins of the word comet. When comets appear in the sky, they don’t look like a normal star. ...

    A 4 billion-year-old meteorite from Mars that caused a splash here on Earth decades ago contains no evidence of ancient, primitive Martian life after all, scientists reported Thursday.
  • 2021-10-29
    Astrobiology is a scientific field that studies the origin,evolution, and distribution of life and habitability in the universe. Mars is the most promising planet for the discovery of extraterrestrial life in the solar system; thus, exploration of Martian life and habitable environment have been a special focus in planetary science.

    Transporting a single brick to Mars can cost more than a million British pounds—making the future construction of a Martian colony seem prohibitively expensive. Scientists at The University of Manchester have now developed a way to potentially overcome this problem, by creating a concrete-like material made of extra-terrestrial dust along ...

    NASA is making final preparations for its Perseverance Mars rover to collect its first-ever sample of Martian rock, which future planned missions will transport to Earth. The six-wheeled geologist is searching for a scientifically interesting target in a part of Jezero Crater called the "Cratered Floor Fractured Rough."
  • 2021-07-12
    Scientists have discovered a new type of star dust whose composition indicates that it formed during a rare form of nucleosynthesis (the process through which new atomic nuclei are created) and could shed new light on the history of water on Earth.
  • 2022-01-13
    Organic molecules found in a meteorite that hurtled to Earth from Mars were synthesized during interactions between water and rocks that occurred on the Red Planet about 4 billion years ago, according to new analysis led by Carnegie's Andrew Steele and published by Science.

    Megaripples, intermediate-scale bedforms caused by the action of the wind, have been studied extensively and thought to be largely inactive relics of past climates, save for a few exceptions. A new paper by Planetary Science Institute Research Scientist Matthew Chojnacki shows that abundant megaripple populations were identified across the north ...

    The Mars 2020 Perseverance Rover is collecting samples in search of signs of ancient microbial life, which would advance NASA's quest to explore the past habitability of Mars. The samples are set to return to Earth no earlier than 2031, as part of the Mars Sample Return campaign being planned ...

    Don't look now—but we are currently experiencing a rash of stories about a forthcoming global catastrophe. But in a change from reports of pandemics and climate change, this global catastrophe is produced by the impact of a giant asteroid. Or comet. Or both. This may feel extra ominous given the ...

    Astronomers ended 2021 on a high with the launch on December 25 of the James Webb Space Telescope, a joint mission between the European Space Agency, Nasa and the Canadian Space Agency. It was a relief to hear that the precision drives that opened up the complex sunshield, which is ...

Mazliet vēstures

Kopš meteorītikas zinātnes dzimšanas pagājuši 227 gadi.
Pirmais zināmais meteorīts Latvijas teritorijā nokrita pirms 201 gada.
Otrais zināmais meteorīts Latvijas teritorijā nokrita pirms 158 gadiem.
Trešais zināmais meteorīts Latvijas teritorijā nokrita pirms 157 gadiem.
Pēdējais zināmais meteorīts Latvijas teritorijā nokrita pirms 131 gada.
Pirmais meteorītikai veltītais muzejs Latvijā dibināts pirms 6 gadiem.

Meteoriti.LV vietne tiks pakāpeniski papildināta ar plašu pamatinformāciju par meteorītiku un ar to saistitām astronomijas nozarēm. Uzzināsiet, vai "meteorīti dabā sastopami retāk par dimantiem", cik tie ir veci un kāda ir to izcelsme. Atradīsiet atbildes uz jautājumiem: Vai meteorīti ir bīstami? Kādi meteorīti atrodami Latvijā un kur tos var apskatīt? Vai Latvijā ir vērts meklēt meteorītus? Ko meteorītu izpēte pastāsta mums par Zemes un Saules sistēmas izcelšanos? Ceram, ka tas radīs vēlmi arī jums pašiem novērot Zemes kosmiskos viesus - meteorus, un, varbūt, pat kļūt par īstiem meteorītu medniekiem!
Veiksmīgu novērošanu!
