Meteoriti.LV - par meteorītiku Latvijā un pasaulē: aktuālā informācija, izpēte, meteorītu kolekcija - Meteorītu muzejs.

No 2022. gada ekonomisko sadārdzinājumu dēļ, Meteorītu muzejs ir spiests ieviest minimālo sensa apmeklējuma maksu 10,00€ apmērā! Cenšoties saglabāt plašu mūsu zinātnisko resursu pieejamību, esam priecīgi arī turpmāk 2023. gadā nodrošināt ģimenes un vairāku apmeklētāju grupas gadījumā iepriekšējās cenu atlaides!

    Another tiny asteroid on a collision course with Earth was detected over the weekend, and JPL’s CNEOS Scout system accurately predicted where and when the impact would happen, well before it actually occurred.
  • 2023-01-25
    On Thursday, Jan. 26, a small near-Earth asteroid will have a very close encounter with our planet. Designated 2023 BU, the asteroid will zoom over the southern tip of South America at about 4:27 p.m. PST (7:27 p.m. EST) only 2,200 miles (3,600 kilometers) above the planet’s surface and well ...

    In the early hours of Saturday, Nov. 19, the skies over southern Ontario, Canada, lit up as a tiny asteroid harmlessly streaked across the sky high in Earth’s atmosphere, broke up, and likely scattered small meteorites over the southern coastline of Lake Ontario. The fireball wasn’t a surprise. Roughly 1 ...

    Hosted by JPL’s Center for Near Earth Object Studies, the data can be used by the science community to better understand how asteroids break up when entering the atmosphere.
  • 2022-03-29
    (29075) 1950 DA is a kilometer-sized asteroid that will make a close approach to Earth in 2880 and, because of the corresponding impact probability and size, has ranked at the top of the Sentry risk list since 2014.
  • 2022-03-15
    A small asteroid hit Earth’s atmosphere over the Norwegian Sea before disintegrating on March 11, 2022. But this event wasn’t a complete surprise: Astronomers knew it was on a collision course, predicting exactly where and when the impact would happen.
  • 2021-12-06
    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.
  • 2021-09-03
    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 ...

    London, UK (SPX) Mar 29, 2023 Asteroids sharing their orbits with the planet Neptune have been observed to exist in a broad spectrum of red colour, implying the existence of two populations of asteroids in the region, according to a new study by an international team of researchers. The research is ...
  • 2023-03-30
    Pasadena CA (JPL) Mar 30, 2023 NASA's Psyche mission, which will explore a metal-rich asteroid of the same name, is on track to launch in October 2023 after a one-year delay to complete critical testing. The launch period will open Oct. 5 and close Oct. 25. The asteroid, which lies in ...

    Mars is one of the most studied planets in our solar system, second only to Earth. Signs point to the red planet once existing as a habitable world like our own, mustering intense fascination from scientists to understand the history of Mars' environment and how it came to its present ...
  • 2023-03-30
    A team of planetary scientists at Universidad de Alicante, in Spain, has found that the asteroid Didymos may be spinning so fast that it is flinging off rubble from near its equator. In their paper published in the journal Icarus, the group describes their study of the asteroid and explain ...

    A large asteroid will safely zoom between Earth and the Moon on Saturday, a once-in-a-decade event that will be used as a training exercise for planetary defense efforts, according to the European Space Agency.
  • 2023-03-24
    NASA's OSIRIS-REx spacecraft is cruising back to Earth with a sample it collected from the rocky surface of asteroid Bennu. When its sample capsule parachutes down into the Utah desert on Sept. 24, OSIRIS-REx will become the United States' first-ever mission to return an asteroid sample to Earth.
  • 2023-03-24
    There's a reason Jezero Crater was chosen as the landing site for the Perseverance Rover: it is considered one of the likeliest places to find any evidence if Mars was ever habitable for long periods of time. In this great new flyby video from ESA, you can get a birds-eye ...

    The cohesive force of asteroid particles influence microgravity and can be evaluated under several assumptions of particle size and their sensitivity to particle shape. Approximately hundreds of kilograms of material fall on to Earth's atmosphere daily from space, and filter down as tiny grains and fine dust. Many meteorites that ...

    If you've ever seen a shooting star, you might have seen a meteor on its way to Earth. Those that land here can be used to peek back in time, into the far corners of outer space or at the earliest building blocks of life. Scientists have conducted some of ...

    When the first interstellar comet ever seen in our solar system was discovered in 2017, one characteristic -- an unexplained acceleration away from the sun -- sparked wild speculation, including that it was an alien spacecraft. An astrochemist found a simpler explanation and tested it with an astronomer: in interstellar ...

    Following enormous collisions, such as asteroid impacts, some amount of material from an impacted world may be ejected into space. This material can travel vast distances and for extremely long periods of time. In theory this material could contain direct or indirect signs of life from the host world, such ...

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!
