Remains of a Modern Glacier found near Mars’ Equator implies Water Ice possibly present at Low Latitudes on Mars even today

If there is still water ice preserved at shallow depths at a low latitude on Mars, there would be implications for science and human exploration.

In a groundbreaking announcement at the 54th Lunar and Planetary Science Conference held in The Woodlands, Texas, scientists revealed the discovery of a relict glacier near Mars’ equator. Located in Eastern Noctis Labyrinthus at coordinates 7° 33′ S, 93° 14′ W, this finding is significant as it implies the presence of surface water ice on Mars in recent times, even near the equator. This discovery raises the possibility that ice may still exist at shallow depths in the area, which could have significant implications for future human exploration.

‘Terminator Zones’ on Distant Planets could harbor life

'Terminator zones' on distant planets could harbor life, astronomers say
Some exoplanets have one side permanently facing their star while the other side is in perpetual darkness. The ring-shaped border between these permanent day and night regions is called a “terminator zone.” In a new paper in The Astrophysical Journal, physics and astronomy researchers at UC Irvine say this area has the potential to support extraterrestrial life.

These in-between regions could be prime sites for liquid water. In a new study, University of California, Irvine astronomers describe how extraterrestrial life has the potential to exist on distant exoplanets inside a special area called the “terminator zone,” which is a ring on planets that have one side that always faces its star and one side that is always dark.

“These planets have a permanent day side ...

Evidence that Venus is Volcanically Active

Image from research paper.
The panels show the east-looking first (A) and west-looking second (B) images of the vent.

Venus appears to have volcanic activity, according to a new research paper that offers strong evidence to answer the lingering question about whether Earth’s sister planet currently has eruptions and lava flows.

Venus, although similar to Earth in size and mass, differs markedly in that it does not have plate tectonics. The boundaries of Earth’s moving surface plates are the primary locations of volcanic activity.

New research by University of Alaska Fairbanks Geophysical Institute research professor Robert Herrick revealed a nearly 1-square-mile volcanic vent that changed in shape and grew over eight months in 1991...

Where did Earth’s Water come from? Not Melted Meteorites, according to scientists

The dashed white line in this illustration shows the boundary between the inner solar system and outer solar system, with the asteroid belt positioned roughly in between Mars and Jupiter. A bubble near the top of the image shows water molecules attached to a rocky fragment, demonstrating the kind of object that could have carried water to Earth.

Water makes up 71% of Earth’s surface, but no one knows how or when such massive quantities of water arrived on Earth.

A new study published in the journal Nature brings scientists one step closer to answering that question...
