ASTEROID 16 PSYCHE MIGHT NOT BE WHAT SCIENTISTS EXPECTED

asteroid 16 psyche

The widely studied metallic asteroid known as 16 Psyche was long thought to be the exposed iron core of a small planet that failed to form during the solar system’s earliest days. But new University of Arizona-led research suggests that the asteroid might not be as metallic or dense as once thought and hints at … Read more

SECRETS OF ASTEROID RYUGU

Ryugu’s interaction with the sun changes what we know about asteroid history. In February and July of 2019, the Hayabusa2 spacecraft briefly touched down on the surface of near-Earth asteroid Ryugu. The readings it took with various instruments at those times have given researchers insight into the physical and chemical properties of the 1-kilometer-wide asteroid. These findings could help expla

WHY STUDY ASTEROIDS?

The scientific interest in asteroids is largely due to their status as the remnant debris from the inner solar system formation process. Because some of these objects can collide with the Earth, asteroids are also important for having significantly modified the Earth’s biosphere in the past. They will continue to do so in the future. … Read more

Asteroids, Comets & Meteors | What’s the Difference Between Asteroids, Comets & Meteors?

We all know space rocks, but what about the rocks in space? Asteroids, Comets and Meteors are hurtling through the solar system. So how do you tell them apart and which rocks could hit our planet?Comets pass near Earth but they never make it to the surface. These cosmic snowballs from overtime in the outer reaches … Read more

How Star Making Process Is Polluting The Cosmos?

The DUVET Survey: Direct Te-based Metallicity Mapping of Metal-enriched Outflows and Metal-poor Inflows in Markarian 1486

A team of astronomers at the ARC Center of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D) found that galaxies pollute the environment they exist in. Alex Cameron and Deanne Fisher lead researcher team used a new imaging system, at WM Keck Observatory in Hawaii to confirm that what flows into a galaxy … Read more

A Tail From Collapse Of Comet ATLAS

A TAIL FROM COLLAPSE OF COMET ATLAS

Comet ATLAS, also known as C/2019 Y4 ATLAS, was first discovered on December 28, 2019, by a reflecting telescope atop Mauna Loa in Hawaii as part of the Asteroid Terrestrial-impact Last Alert System (ATLAS). By May 2020 Comet ATLAS was visible to the naked eye as it grew brighter, the Long-period comet ATLAS disintegrated just … Read more

COULD A GIANT SPACE UMBRELLA HELP COOL DOWN OUR PLANET?

It’s a radical idea, and it just might just work. Reducing the amount of light reaching our planet could cool the Earth quickly, even with rising carbon dioxide levels. While the asteroid which helped wipe out the dinosaurs blocked out 90% of the Sun’s rays, we would need to divert just 2-4%, it’s believed, to take the Earth back to its pre-industrial climate.

New Kaleidoscopic Map Details the Geology of the Moon

This animation shows a rotating globe of the new Unified Geologic Map of the Moon with shaded topography from the Lunar Orbiter Laser Altimeter (LOLA). This geologic map is a synthesis of six Apollo-era regional geologic maps, updated based on data from recent satellite missions. It will serve as a reference for lunar science and future human missions to the Moon. Credit: NASA/GSFC/USGS.

Accretion Of A Giant Planet Onto A White Dwarf Star

The Neptune-sized planet, which orbits an Earth-sized star, is being slowly evaporated by the white dwarf, causing the planet to lose some 260 million tons of material every day. For the first time, astronomers have discovered evidence for a giant planet orbiting a tiny, dead white dwarf star. And, surprisingly, the Neptune-sized planet is more … Read more

A Nearby Gamma Ray Burst Might Have Caused The Ordovician Extinction

Despite the obvious doom and gloom associated with mass extinctions, they have a tendency to capture our imagination. After all, the sudden demise of the dinosaurs, presumably due to an asteroid strike, is quite an enthralling story. But not all mass extinctions are quite as dramatic and not all have an easily identified culprit. The … Read more
