    This eerie, dark silhouette is a cometary globule designated GN 16.43.7.01. Despite their name, cometary globules have nothing to do with comets, beyond having a similar shape of a dusty head with a tail.

    Planetary defense has gone from a relatively fringe topic with little funding to one with NASA missions demonstrating the ability to change an asteroid's orbit. Jeff Foust reviews a book that examines those efforts to detect and defend Earth from asteroids, and the need to do more.
  • 2024-10-14
    ESA last week launched its Hera mission to the same asteroid that NASA's DART spacecraft collided with two years ago. Jeff Foust reports on the struggles the Hera project faced getting the spacecraft launched, from funding challenges to a hurricane.

  • 2024-04-29
    Mars scientists hoped they would have a better idea of when and how they would get samples back from Mars after NASA completed an internal study of the Mars Sample Return program. Instead, as Jeff Foust reports, NASA is now turning to industry for help on how to reduce the ...
  • 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

  • 2024-12-05
    China's growing presence in space has been undeniable since the turn of the century. Between sending the first "taikonaut" to space in 2003 (Yang Liwei), launching the first Chinese robotic mission to the moon (Chang'e-1) in 2007, and the deployment of their Tiangong space station between 2021 and 2022, China ...

    Six years ago, NASA's Dawn mission communicated with Earth for the last time, ending its exploration of Ceres and Vesta, the two largest bodies in the asteroid belt. Since then, Ceres —a water-rich dwarf planet showing signs of geological activity— has been at the center of intense debates about its ...
  • 2024-12-03
    Researchers have found that water on Comet 67P/Churyumov–Gerasimenko has a similar molecular signature to the water in Earth's oceans. Contradicting some recent results, this finding reopens the case that Jupiter-family comets like 67P could have helped deliver water to Earth.
  • 2024-11-22
    Panspermia is the hypothesis that life can survive the transfer between planetary bodies as a secondary path for life to get started on planets throughout a solar system.

    Chondritic meteorites (chondrites) are some of the oldest rocks in our solar system, forming 4.5 billion years ago. Therefore, their primitive composition means that they offer a window into the origins of planet formation, particularly as their major elements (heavier than hydrogen and helium, including oxygen, silicon, magnesium, iron and ...
  • 2024-12-09
    The first dark comet—a celestial object that looks like an asteroid but moves through space like a comet—was reported less than two years ago. Soon after, another six were found. In a new paper, researchers announce the discovery of seven more, doubling the number of known dark comets, and find ...

    When 'Oumuamua traversed our solar system in 2017 it was the first confirmed Interstellar Object (ISO) to do so. Then in 2019, Comet 2l/Borisov did the same thing. These are the only two confirmed ISOs to visit our solar system. Many more ISOs must have visited in our solar system's ...

  • 2024-12-14
    New research on Comet 67P indicates that its water may be similar to Earth’s, contradicting earlier findings by Rosetta’s mission which showed high deuterium levels. This suggests that comets could have played a role in delivering water to Earth, as dust effects in previous measurements may have skewed results. Origin ...

GADA METEORĪTS
2024
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!
