    When we think of Mars as the “Red Planet”, the image that comes to mind is just that - a lot of red. That comes from the oxidization of the dust and rocks that cover the planet's surface, but there are some instances where the Red Planet still has a ...

    Comets are known for providing breathtaking observations of their long and shiny tails when they travel too close to the Sun. This happens because comets are made of ice and primarily orbit far from the Sun, but as their icy core heats up it evaporates, resulting in the aforementioned breathtaking ...
  • 2026-07-24
    The worlds of the Solar System offer up exciting and (so far) mostly pristine places for planetary scientists to study. As space missions continue to travel to Mars, Europa, asteroids, and other worlds, questions keep coming up about keeping them safe for continued exploration and observations.
  • 2026-07-22
    Martian dust storms are some of the most fascinating and mysterious planetary surface processes ever observed, as Earth, Mars, and Saturn’s moon Titan are the only known planetary bodies to have active dust storms. However, the major difference for Mars is its dust storms can blanket the entire planet at ...

    NASA's Psyche mission used a gravity assist maneuver at Mars to gain velocity and adjust its trajectory to its eventual target. The asteroid 16 Psyche is a metal-rich asteroid that may be the remnant rocky core of a protoplanet. The flyby not only shepherded the spacecraft on to its target, ...

    Our ability to track and visualize small rocks in space is still improving. And occasionally we’ll find a space rock that will remind us of that fact. One such rock is detailed in a new paper, led by Davide Farnocchia of NASA’s Jet Propulsion Laboratory, and recently published in Nature ...
  • 2026-07-21
    On Earth, it’s hard to track events that reshape its surface, as the surface itself is being reshaped constantly by weather and tectonic or volcanic upheavals. However, the Moon is much more static, and scientists have been slowly unraveling a pattern that is noticeable in its craters - that something ...
  • 2026-07-21
    A low-number periodic comet is stalking our fair planet this summer, and putting on its best show of several generations. We’re talking about Comet 10P/Tempel. The comet is currently loitering in the early dawn sky, presenting a good target for large binoculars or a small telescope. But act fast, as ...

    A new analysis of the the oldest known Mars meteorite, Teghaza 001, reveals evidence for a granite-like crust and the start of the loss of water on early Mars. The post Oldest Mars meteorite reveals Mars lost its water early first appeared on EarthSky.

    EarthSky's visible planets and night sky guide. This evening, the gibbous moon lies near red Antares. And it's meteor season! Watch a video here. The post Visible planets and night sky guide for July and August first appeared on EarthSky.

    The peak of the Delta Aquariid meteor shower is late July. But the shower rambles along steadily for weeks and intermingles with the famous Perseids. The post Delta Aquariid meteor shower: All you need to know in 2026 first appeared on EarthSky.

    Ancient samples from the moon's far side are helping scientists uncover how asteroid impacts shaped the early solar system. The findings challenge decades of thinking about when those impacts occurred and offer new insights into the conditions that influenced Earth's evolution.

    Rising mantle temperatures and two heat surges may explain why some Hawaiian volcanoes grew exceptionally large. A 3500 km (2200 mile) trail of volcanoes records the Pacific plate’s slow passage over the Hawaiian hotspot. Instead of cooling through time as geologists have generally expected, the mantle plume beneath this chain ...

    Earth may have been recycling surface water through its deep interior more than three billion years ago. In the Pilbara region of Western Australia, volcanic rocks more than three billion years old preserve traces of a journey once considered unlikely. Their chemistry suggests that water from Earth’s surface had already ...

    China’s Tianwen-1 orbiter captured a faint but remarkable view of 3I/ATLAS as the interstellar comet raced past Mars. The images reveal its tail and glowing coma, offering scientists a glimpse of material born beyond our solar system.
  • 2026-07-19
    Researchers have created cosmic dust from scratch by recreating space-like conditions inside glass tubes. The dust contains complex carbon-rich molecules built from elements essential to life and produces infrared signals similar to real material found in space. By studying these laboratory samples, scientists can explore how organic chemistry unfolds around ...

    The asteroid that wiped out the dinosaurs was likely an exceptionally rare CO chondrite from a distant region of the solar system. Its unusual chemistry suggests that planet-cooling dust and debris, rather than sulfur inside the asteroid, may have delivered the deadliest blow.
  • 2026-07-18
    A catastrophic asteroid breakup may have triggered a huge wave of impacts across the inner solar system about 800 million years ago. The debris was launched from near a gravitational gateway controlled by Jupiter, sending fragments toward Earth, the Moon, and Mars. The bombardment may explain ancient lunar craters and ...

    NASA's Perseverance rover has reached an impressive new milestone on Mars, completing the equivalent of a full marathon by driving 26.2 miles (42.195 kilometers) across the Red Planet. It accomplished the feat in just five years and four months, reaching the distance on its 1,890th Martian day, less than half ...
  • 2026-07-09
    The hunt for ancient life on Mars just got an important test run. Scientists confirmed that the Rosalind Franklin rover's sophisticated instrument can detect subtle differences in two stable molecules that could preserve evidence of past life for billions of years. But the team also uncovered a surprise: organic molecules ...

    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!
