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!

  • 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 ...
  • 2022-04-07
    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 ...
  • 2021-10-07
    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 ...
  • 2021-03-25
    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 ...

    Comet 2022 E3 (ZTF) is of special interest this January as at the time of writing (mid-November) it appears well on-course to be an easy binocular object and perhaps a marginal naked-eye comet.
  • 2022-12-13
    Watch out tonight (13th/14th) and tomorrow night (14th/15th) for the welcome return of the Geminid meteor shower.

  • 2023-02-06
    While astronomers and engineers were trying to calibrate one of the James Webb Space Telescope’s instruments last summer, they serendipitously found a previously unknown small 100–200-meter (300-600 ft) asteroid in the main asteroid belt. Originally, the astronomers deemed the calibrations as a failed attempt because of technical glitches. But they ...

    MSL Curiosity is going about its business exploring Mars. The high-tech rover is currently exploring the sulphate-bearing unit on Mt. Sharp, the central peak in Mars’ Gale Crater. Serendipity placed a metal meteorite in its path. The meteorite is made mostly of nickel and iron, and it has a name: ...

    Paris (ESA) Feb 07, 2023 A previously unknown 100-200-metre asteroid - roughly the size of Rome's Colosseum - has been detected by an international team of European astronomers using the NASA/ESA/CSA James Webb Space Telescope. Their project used data from the calibration of the Mid-InfraRed Instrument (MIRI), in which the team ...

    A previously unknown 100-to-200-meter asteroid—roughly the size of Rome's Colosseum—has been detected by an international team of European astronomers using the NASA/ESA/CSA James Webb Space Telescope. Their project used data from the calibration of the Mid-InfraRed Instrument (MIRI), in which the team serendipitously detected an interloping asteroid.
  • 2023-02-01
    Comet C/2022 E3 (ZTF) today makes its closest approach to Earth before likely leaving our solar system forever. At billions of years old and not seen since Neanderthals roamed, the green comet continues to intrigue as it grows an apparent third tail and unexpectedly—but intriguingly—failed to wow scientists when observed ...

    Mars is a dusty planet. From tiny dust devils to vast storms that shroud the planet, dust is a constant challenge for research missions. That was especially true for Ingenuity, the rotorcraft that since February 2021 has been exploring Mars alongside NASA's Perseverance rover. Now, researchers at Stevens Institute of ...

    When a Southwest Research Institute scientist discovered surprising evidence that Saturn's smallest, innermost moon could generate the right amount of heat to support a liquid internal ocean, colleagues began studying Mimas' surface to understand how its interior may have evolved. Numerical simulations of the moon's Herschel impact basin, the most ...

    One of the main jobs for the Perseverance Mars rover past few weeks has been collecting carefully selected samples of Mars rock and soil. These samples have been placed and sealed in special sample tubes and left in well-identified places so that a future sample return mission can collect them ...

    Earth's potassium arrived by meteoritic delivery service finds new research led by Carnegie's Nicole Nie and Da Wang. Their work, published in Science, shows that some primitive meteorites contain a different mix of potassium isotopes than those found in other, more-chemically processed meteorites. These results can help elucidate the processes ...

GADA METEORĪTS
2023
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!
