    In and around the vast Imbrium Basin is a very fertile area for lunar observers. For our Imbrium expedition let’s zero in on its magnificent mountain ranges and great selection of impact craters.

    On September 26th, 2022, NASA’s Double Asteroid Redirection Test (DART) collided with the asteroid Dimorphos, a moonlet that orbits the larger asteroid Didymos. The purpose of this test was to evaluate a potential strategy for planetary defense. The demonstration showed that a kinetic impactor could alter the orbit of an ...

    Universe Today has had some fantastic discussions with researchers on the importance of studying impact craters, planetary surfaces, exoplanets, astrobiology, solar physics, comets, planetary atmospheres, and planetary geophysics, and how these diverse scientific fields can help researchers and the public better understand the search for life beyond Earth. Here, we ...

    An asteroid created a large Martian crater called Corinto, about 2 million years ago. Debris from the impact also created 2 billion smaller craters on Mars. The post How 2 billion craters on Mars were created by 1 asteroid first appeared on EarthSky.


  • 2024-02-12
    Concerns about the budget and plans for NASA's Mars Sample Return (MSR) program came to a head last week when JPL laid off more than 500 employees, citing budget uncertainty about the program. Jeff Foust reports on the issues that have put the future of MSR into question for some.
  • 2024-02-05
    Ingenuity, whose mission ended last month, was a first-of-its-kind Mars helicopter with no guarantees more will follow soon. Ari Allyn-Feuer discusses how sending a large number of similar helicopters could advance Martian exploration in novel ways.
  • 2023-09-25
    On Sunday, NASA's OSIRIS-REx spacecraft returned to Earth, dropping off a capsule containing samples collected from the asteroid Bennu. Jeff Foust reports on the success of the first part of NASA's "Asteroid Autumn" that includes a launch and a flyby.
  • 2023-09-11
    Last month, a paper claimed to have found evidence for interstellar meteorites at the bottom of the Pacific, a claim other scientists have treated skeptically. Jeff Foust review a book by the scientist who is the lead author of that study and other efforts using science to look for interstellar ...

    The Fox reality TV series "Stars on Mars" wrapped up recently with one "celebronaut" crowned as winner. The series, Dwayne Day explains, also provided useful lessons for real missions to the Red Planet.
  • 2023-07-17
    A Senate appropriations bill released last week would slash funding for NASA's Mars Sample Return program and threaten it with cancellation. Jeff Foust reports on the new fiscal challenges that efforts to return samples from Mars have encountered.

  • 2024-03-19
    Universe Today has examined the importance of studying impact craters, planetary surfaces, exoplanets, astrobiology, solar physics, comets, and planetary atmospheres, and how these intriguing scientific disciplines can help scientists and the public better understand how we are pursuing life beyond Earth.
  • 2024-03-07
    Sound waves thought to be from a 2014 meteor fireball north of Papua New Guinea were almost certainly vibrations from a truck rumbling along a nearby road, new Johns Hopkins University-led research shows. The findings raise doubts that materials pulled last year from the ocean are alien materials from that ...
  • 2024-02-26
    Life on our planet appeared early in Earth's history. Surprisingly early, since in its early youth our planet didn't have much of the chemical ingredients necessary for life to evolve. Since prebiotic chemicals such as sugars and amino acids are known to appear in asteroids and comets, one idea is ...
  • 2024-02-23
    Universe Today has investigated the importance of studying impact craters, planetary surfaces, exoplanets, and astrobiology, and what these disciplines can teach both researchers and the public about finding life beyond Earth. Here, we will discuss the fascinating field of solar physics (also called heliophysics), including why scientists study it, the ...
  • 2024-02-13
    Using data from the retired Stratospheric Observatory for Infrared Astronomy (SOFIA)—a joint project of NASA and the German Space Agency at DLR—Southwest Research Institute scientists have discovered, for the first time, water molecules on the surface of an asteroid. Scientists looked at four silicate-rich asteroids using the FORCAST instrument to ...

    Curtin University-led research has discovered a rare dust particle trapped in an ancient extra-terrestrial meteorite that was formed by a star other than our sun.
  • 2024-03-27
    On March 25, 2024, a citizen scientist in the Czech Republic spotted a comet in an image from the Solar and Heliospheric Observatory (SOHO) spacecraft, which has now been confirmed to be the 5,000th comet discovered using SOHO data. SOHO has achieved this milestone over 28 years in space, even ...

    A Mount Everest-sized 'devil' comet making its first visit to the inner solar system in more than 70 years could be visible to the naked eye over the next few weeks.

    Billions of years ago, Mars was home to abundant water, and its Gale crater contained a lake. Gradually, the climate changed, drying the red planet and creating the dusty desert world we know today.
  • 2024-03-21
    The dust of comets fills the space between the planets, collectively called the zodiacal cloud. Still, severe breakdown has reduced that dust in size so much that it now scatters sunlight efficiently, causing the faint glow in the night sky known as the "zodiacal light."
  • 2024-03-21
    Using observations made with the Gran Telescopio Canarias (GTC) a study led from the Instituto de Astrofísica de Canarias (IAC) and the Universidad Complutense de Madrid (UCM) has confirmed that the asteroid 2023 FW14, discovered last year, is accompanying the red planet in its journey round the sun, ahead of ...

    There are plenty of craters on Mars, especially when compared to Earth. That is primarily thanks to the lack of weathering forces and strong plate tectonics that disrupt the formations of such impacts on our home planet. However, not all impact craters on Mars are directly caused by asteroid impacts. ...

GADA METEORĪTS
2020
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!
