Study: NASA's Mars rovers found manganese oxides in Gale's rocks
Updated : 3 years, 2 months ago IST
When NASA's Mars rovers found manganese oxides in rocks in the Gale and Endeavor craters on Mars in 2014, the discovery sparked some scientists to suggest that the red planet might have once had more oxygen in its atmosphere billions of years ago.

Loon stratospheric balloons confirm wind data from Aeolus: Research
Updated : 3 years, 2 months ago IST
ESA's novel Aeolus satellite reliably measures wind speed also in higher air layers and thus in a region of the atmosphere where other direct global wind measurements are relatively sparse. This is the result of a study in which data from the satellite were compared with wind observations fr

Changes in Earth's orbit may have triggered ancient warming event
Updated : 3 years, 2 months ago IST
Changes in Earth's orbit that favored hotter conditions may have helped trigger a rapid global warming event 56 million years ago that is considered an analogue for modern climate change, according to an international team of scientists.

New ways microbes might help humans build colonies on Moon, Mars: Research
Updated : 3 years, 2 months ago IST
Researchers at the University of California, Irvine have been motivated to consider new ways that microbes can assist humans in colonising the Moon and Mars by studying the biochemical process by which cyanobacteria absorb nutrients from rocks in Chile's Atacama Desert.

Seismic waves from marsquake detected, revealed possible past meteoroid im
Updated : 3 years, 2 months ago IST
The largest earthquake ever detected on Mars has revealed layers in its crust that could indicate past collision with a massive object, such as a meteoroid. Previous data have suggested the past occurrence of a large impact, and the findings offer evidence that might support this hypothesis.

Webb Space Telescope reveals previously shrouded newborn stars
Updated : 3 years, 2 months ago IST
Rice University astronomer Megan Reiter and colleagues took a "deep dive" into one of the first images from NASA's James Webb Space Telescope and were rewarded with the discovery of telltale signs from two dozen previously unseen young stars about 7,500 light years from Earth.

Study confirms light from outside our galaxy is brighter than expected
Updated : 3 years, 2 months ago IST
Washington [US], December 17 (ANI): Scientists analyzed new measurements showing that the light emitted by stars outside our galaxy is two to three times brighter than the light from known populations of galaxies, challenging assumptions about the number and environment of stars in the unive

Webb telescope 'Pearls' project brings exquisite views of distant galaxies
Updated : 3 years, 2 months ago IST
For decades, the Hubble Space Telescope and ground-based telescopes have provided us with spectacular images of galaxies. This all changed when the James Webb Space Telescope (JWST) launched in December 2021 and successfully completed commissioning during the first half of 2022. For astro

Astronomers find that two exoplanets may be mostly water
Updated : 3 years, 2 months ago IST
A team led by UdeM astronomers has found evidence that two exoplanets orbiting a red dwarf star are "water worlds," planets where water makes up a large fraction of the volume. These worlds, located in a planetary system 218 light-years away in the constellation Lyra, are unlike any planets
