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 2022. gadā nodrošināt ģimenes un vairāku apmeklētāju grupas gadījumā iepriekšējās cenu atlaides!

  • 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.
  • 2020-08-18
    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 ...
  • 2020-04-28
    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.
  • 2020-04-28
    A relatively small asteroid, about 4 to 8 meters in diameter, will fly safely past Earth just before 3pm today, Apr. 28 (Eastern U.S. time). NASA is tracking the object, but orbit calculations ruled out any chance that the near-Earth object could pose a threat to our planet.
  • 2020-02-27
    A small object, presumed to be a tiny asteroid, has been discovered in a distant orbit about the Earth, a highly unusual circumstance, since asteroids normally orbit the Sun. The new “mini-moon” has been given the asteroid designation 2020 CD3, but in view of its strange orbit, there is a ...
  • 2019-09-12
    A newly discovered comet has excited the astronomical community this week because it appears to have originated from outside the solar system. The object - designated C/2019 Q4 (Borisov) - was discovered on Aug. 30, 2019, by Gennady Borisov at the MARGO observatory in Nauchnij, Crimea. The official confirmation that ...


  • 2022-09-28
    Here’s one of the best videos we’ve seen of the last minutes of the Double Asteroid Redirection Test (DART) mission as it headed towards and slammed into the asteroid Dimorphos. This stabilized version of the last five-and-a-half minutes of images leading up to DART’s intentional collision with the asteroid was ...
  • 2022-09-27
    The first-ever planetary defense technology demonstration mission successfully conducted its mission, slamming into the surface of a distant asteroid and going out in a blaze of glory. NASA’s Double Asteroid Redirection Test (DART) spacecraft acted as a kinetic impactor, colliding with the small and harmless asteroid Dimorphos on September 26 ...

  • 2022-09-28
    A new study from scientists at NASA's Goddard Space Flight Center "erased craters" to better understand the moon's wandering poles over time. The post Moon’s wandering poles revealed in new study first appeared on EarthSky.


  • 2022-09-29
    Beijing, China (SPX) Sep 29, 2022 A new radar image obtained by China's Mars rover Zhurong provides insights into the surface structure of the Utopia Planitia basin. The findings - which reveal multiple sub-layers suggestive of sediment deposition following episodic flooding millions of years ago - may improve our understanding of ...
  • 2022-09-29
    Ithaca NY (SPX) Sep 29, 2022 When NASA's 990-pound Dragonfly rotorcraft reaches the Selk crater region - the mission's target touchdown spot - on Saturn's moon Titan in 2034, Cornell's Lea Bonnefoy '15 will have helped to make it a smooth landing. Bonnefoy and her colleagues assisted the future arrival by ...
  • 2022-09-29
    Pasadena CA (JPL) Sep 22, 2022 The SHERLOC and PIXL proximity science instruments on Perseverance have enabled more detailed observations of Martian chemistry and minerology than ever before. PIXL can isolate features as small as a grain of sand. To achieve this, these instruments on the end of the robotic arm ...

  • 2022-09-23
    An international team including a researcher from Lawrence Livermore National Laboratory (LLNL) has determined that one specific particle on the asteroid Ryugu can shed light on the unaltered initial materials from its parent body.

GADA METEORĪTS
2022
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!
