Dark streaks on Mars may be caused by salts and melting ice
Researchers at the SETI Institute say that unusual dark streaks on sun-facing slopes on Mars, debated about for years, may be small landslides caused by a combination of salts and melting ice just below the surface.

What’s the weather like on Titan?
Most of the planets in our solar system have some sort of atmosphere and many have dynamic weather systems. But only one moon in the solar system, Saturn’s large moon Titan, can say the same. Source: https://earthsky.org/space/titan-saturns-moon-weather-seasons-methane-rain-storms…
Substance Found In Antarctic Ice May Solve a Martian Mystery
sciencehabit shares a report from Science Magazine: Researchers have discovered a common martian mineral deep within an ice core from Antarctica. The find suggests the mineral — a brittle, yellow-brown substance known as jarosite — was forged the same way on both Earth and Mars: from dust trapped within ancient ice deposits. It also reveals how important these glaciers were on…
New evidence for multiple ice ages on Mars
Earth has had at least 5 major ice ages. Now it appears Mars – the next planet outward from the sun – has undergone anywhere from half a dozen to 20 ice ages in the past several hundred million years. Source: https://earthsky.org/space/new-evidence-for-multiple-ice-ages-on-mars…
Our world is losing ice at a record rate
The rate at which ice is disappearing across the planet has been speeding up, with 65% since the 1990s, a survey of global ice loss using European Space Agency satellite data reveals. Source: https://earthsky.org/earth/esa-satellites-show-record-rate-ice-loss…
Earth is Losing Ice Faster Today Than in the Mid-1990s, Study Suggests
Earth’s ice is melting faster today than in the mid-1990s, new research suggests, as climate change nudges global temperatures ever higher. From a report: Altogether, an estimated 28 trillion metric tons of ice have melted away from the world’s sea ice, ice sheets and glaciers since the mid-1990s. Annually, the melt rate is now about 57 percent faster than it was…
Mystery of Martian glaciers revealed

The curious case of the “glacier mice” that seem to dance on ice
Fuzzy moss balls that colonise glaciers and move in perfect unison have puzzled scientists for decades. Now, thanks to some painstaking surveillance, they are finally giving up their secrets Source: https://www.newscientist.com/article/mg24833132-900-the-curious-case-of-the-glacier-mice-that-seem-to-dance-on-ice/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Pluto’s landscape more like Earth’s than previously thought
New analysis of data gathered from New Horizons’ 2015 flyby of Pluto shows evidence of Earth-like snow-capped mountains and the potential for glaciers made of methane ice. Source: https://earthsky.org/space/pluto-landscape-more-like-earths-than-previously-thought…
