LAMOST reveals new footprints of the Gaia-Sausage-Enceladus merger event

Beijing, China (SPX) Mar 17, 2021
Looking up at the starry sky, the deep Universe appears quiet and mysterious. It is hard to imagine that the ancient dwarf galaxy Enceladus violently collided and was torn apart by our own Milky Way Galaxy, leaving behind the cries of a whole new generation of children from the hundred-handed giant.

Ancient light illuminates matter that fuels galaxy formation

Ithaca NY (SPX) Mar 17, 2021
Using light from the Big Bang, an international team led by Cornell University and the U.S. Department of Energy's Lawrence Berkeley National Laboratory has begun to unveil the material which fuels galaxy formation.
"There is uncertainty on the formation of stars within galaxies that theoretical models are unable to predict," said lead author Stefania Amodeo, a Cornell postdoctoral researc

ASU scientists determine origin of strange interstellar object

Tempe AZ (SPX) Mar 17, 2021
In 2017, the first interstellar object from beyond our solar system was discovered via the Pan-STARRS astronomical observatory in Hawaii. It was named 'Oumuamua, meaning "scout" or "messenger" in Hawaiian. The object was like a comet, but with features that were just odd enough to defy classification.

SwRI researcher theorizes worlds with underground oceans support, conceal life

San Antonio TX (SPX) Mar 17, 2021
One of the most profound discoveries in planetary science over the past 25 years is that worlds with oceans beneath layers of rock and ice are common in our solar system. Such worlds include the icy satellites of the giant planets, like Europa, Titan and Enceladus, and distant planets like Pluto.

Juno reveals dark origins of one of Jupiter's grand light shows

Pasadena CA (JPL) Mar 17, 2021
New results from the Ultraviolet Spectrograph instrument on NASA's Juno mission reveal for the first time the birth of auroral dawn storms - the early morning brightening unique to Jupiter's spectacular aurorae.
These immense, transient displays of light occur at both Jovian poles and had previously been observed only by ground-based and Earth-orbiting observatories, notably NASA's Hubble

In a comment published in Nature Astronomy, Dr. Nathalie Cabrol, Director of the Carl Sagan Center for Research at the SETI Institute, challenges assumptions about the possibility of modern life on Mars held by many in the scientific community.

New study challenges long-held theory of fate of Martian Water
Write a comment
Pasadena CA (JPL) Mar 17, 2021
Billions of years ago, according to geological evidence, abundant water flowed across Mars and collected into pools, lakes, and deep oceans. New NASA-funded research shows a substantial quantity of its water - between 30 and 99% - is trapped within minerals in the planet's crust, challenging the current theory that due to the Red Planet's low gravity, its water escaped into space.

Scientists unearth meteorite from the birth of the solar system
Write a comment
Scientists believe they have identified a meteorite formed in the first million years of our solar system, making it the oldest known meteor of volcanic origin.
The space rock, which began its journey some 4.5 billion years ago, has already proved an "exceptional" witness to the building blocks of the planets.
Known as Erg Chech 002, the meteorite was discovered in May 2020 by meteor hunters in the Algerian Sahara desert. It had rested undisturbed for "at least 100 years", according to Jean-Alix Barrat, a geochemist at France's Brest University.
In a recent study published in the Proceedings of the National Academy of Sciences journal, Barrat and his colleagues describe its discovery and several rare features.
There are 43 officially documented fragments, but "probably about a hundred" either still in the ground or unaccounted for, said the study.
