Why does this galaxy look older than its years?
To the extent that we can see them, galaxies in the very early universe should look relatively young and unformed. But galaxy ALESS 073.1 is a surprise to astronomers: it looks more mature than we’d have any reason to expect. Why? Source: https://earthsky.org/space/galaxy-looks-older-than-its-years-aless-073-1…
‘Earth wind’ may generate water on the moon
Particles carried from Earth’s poles via our planet’s magnetosphere could be interacting with lunar rocks to create small quantities of water on the moon. Source: https://earthsky.org/space/earth-wind-may-generate-water-on-moon…

Astronomers detect new super-Earth exoplanet orbiting nearby star
Using the radial velocity (RV) technique, astronomers have discovered a new super-Earth alien world as part of the HADES and CARMENES programs. The newfound exoplanet, designated GJ 740 b, orbits a bright star some 36 light-years away and is at least three times more massive than the Earth. The finding is reported in a paper published February 18 on the arXiv…
Nearby black hole Cyg X-1 more massive than thought
New research suggests that the famous black hole Cygnus X-1 – first black hole ever detected and one of the closest to Earth – is farther away and much more massive than previously believed. Source: https://earthsky.org/space/cygnus-x-1-black-hole-more-massive-farther…
Do we all see the same moon phase?
No matter where you are on the globe, we all see the same moon. So why do photos from a distant location sometimes look different from what you’re seeing? Source: https://earthsky.org/astronomy-essentials/do-we-all-see-the-same-moon-phase…
Ultraluminous X-ray pulsar M51 ULX-7 inspected by researchers
Using NASA’s Swift and Chandra space observatories, astronomers have investigated an ultraluminous X-ray pulsar known as M51 ULX-7. The study, detailed in a paper published February 16 on the arXiv pre-print server, sheds more light on the X-ray variability of this source.
