    We long suspected that passing stars are what send distant comets sunward. But could passing stars also change Earth's orbit? A recent study says yes. The post Did passing stars change Earth’s orbit? first appeared on EarthSky.

    Pasadena CA (JPL) Feb 26, 2024 The planning team came in after the weekend to see another beautiful Martian drill hole on the target Mineral King! Mineral King is named after a silver mining district in Sequoia National Park, California. This was a pretty odd-looking rock, with the big overhanging ledges ...

    Paris (ESA) Feb 27, 2024 ESA's Hera spacecraft for planetary defence is being prepared for a journey to the distant asteroid moon Dimorphos orbiting around its parent body Didymos. One of the first features Hera will look for is the crater left on Dimorphos by its predecessor mission DART, which impacted ...

    Pasadena CA (JPL) Feb 27, 2024 On Feb. 2, a large asteroid safely drifted past Earth at a distance of about 1.8 million miles (2.9 million kilometers, or 7 0.5 times the distance between Earth and the Moon). There was no risk of the asteroid - called 2008 OS7 - ...

    Los Angeles CA (SPX) Feb 27, 2024 NASA's groundbreaking OSIRIS-REx mission has set a new benchmark in space exploration by delivering a staggering 4.29 ounces (121.6 grams) of asteroid material to Earth, marking the largest ever asteroid sample collection. The spacecraft's triumphant return on September 24, 2023, with samples from asteroid ...

    Cincinnati OH (SPX) Feb 27, 2024 In the three years since NASA's Perseverance rover touched down on Mars, the NASA science team has made the daily task of investigating the red planet seem almost mundane. The rover and its helicopter sidekick Ingenuity have captured stunning images of Mars and collected 23 ...

  • 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.

  • 2024-02-26
    During the close approach of 2008 OS7 with Earth on Feb. 2, the agency's Deep Space Network planetary radar gathered the first detailed images of the stadium-size asteroid.

    When a star like our sun reaches the end of its life, it can ingest the surrounding planets and asteroids that were born with it. Now, using the European Southern Observatory's Very Large Telescope (ESO's VLT) in Chile, researchers have found a unique signature of this process for the first ...
  • 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 ...

    A comet is set to pass by Earth this spring, and it may be missing its tail.
  • 2024-02-18
    A complex project aimed at retrieving rock and dirt samples from Mars has long been a top priority for NASA, with proponents arguing the mission could answer the age-old question of whether life once existed on the red planet.

    When a star like our Sun reaches the end of its life, it can ingest the surrounding planets and asteroids that were born with it. Now, researchers have found a unique signature of this process for the first time -- a scar imprinted on the surface of a white dwarf ...
  • 2024-02-22
    Scientists suspect Mars once had long-lived rivers, lakes and streams. Today, water on Mars is found in ice at the poles and trapped below the Martian surface. Researchers now reveal that Mars also may have had hydrothermal systems based on the hydrated magnesium sulfate the rover identified in the volcanic ...

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!
