Purported phosphine on Venus more likely to be ordinary sulfur dioxide, new study shows
In September, a team led by astronomers in the United Kingdom announced that they had detected the chemical phosphine in the thick clouds of Venus. The team’s reported detection, based on observations by two Earth-based radio telescopes, surprised many Venus experts. Earth’s atmosphere contains small amounts of phosphine, which may be produced by life. Phosphine on Venus generated buzz that the…
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…
What do redshifts tell astronomers?
A redshift reveals how an object is moving in space and enables astronomers to discover otherwise-invisible planets and the movements of galaxies, and to uncover the beginnings of our universe. Source: https://earthsky.org/astronomy-essentials/what-is-a-redshift…
