    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 ...
  • 2021-03-11
    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 ...
  • 2020-11-12
    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 ...
  • 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.


  • 2021-11-30
    Comet 2021 A1 (LEONARD) has broken out of the cometary pack to brighten up and shine close to naked-eye magnitude. All the indications look good for it at the very least to become a nice object through a pair of binoculars.
  • 2021-11-26
    Pausing on the slopes of Mount Sharp, NASA's Curiosity Mars rover set back two black-and-white panoramas that were colourised to provide an "artistic" view looking back along its recent path with the rim of Gale Crater rising in the distance.
  • 2021-11-24
    A small NASA space probe blasted off from California early Wednesday aboard a SpaceX Falcon 9 rocket on a first-of-its-kind mission to change the orbit of an asteroid, pioneering a technique that may one day be used to divert an asteroid off of a collision course with Earth.

    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.
  • 2021-09-13
    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 ...
  • 2021-07-21
    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."

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!
