Using observations made with the Gran Telescopio Canarias (GTC) a study led from the Instituto de Astrofísica de Canarias (IAC) and the Universidad Complutense de Madrid (UCM) has confirmed that the asteroid 2023 FW14, discovered last year, is accompanying the red planet in its journey round the sun, ahead of Mars and in the same orbit.

With this new member, the group of Trojans that accompany Mars has increased in number to 17. But it shows differences in its orbit and chemical composition which may indicate that it is a captured asteroid, of a primitive type. The results are published in Astronomy & Astrophysics.

If there is life in the solar system beyond Earth, it might be found in the clouds of Venus. In contrast to the planet’s blisteringly inhospitable surface, Venus’ cloud layer, which extends from 30 to 40 miles above the surface, hosts milder temperatures that could support some extreme forms of life.

If it’s out there, scientists have assumed that any Venusian cloud inhabitant would look very different from life forms on Earth...

The total solar eclipse isn’t the only reason to keep your eyes to the sky this year. For the first time in 80 years, a star system 3,000 light years away will be visible to the naked eye thanks to a once-in-a-lifetime nova outburst.

NASA announced that the nova, which will create a “new” star in the night sky, will light up the night sky some time between now and September and be as bright as the North Star. One of only five recurring novae in our galaxy, it will be visible for a week before it fades back down.

Jonathan Blazek, an assistant professor of physics at Northeastern University, says this is an exciting moment for amateur astron...

Dark matter is one of science’s greatest mysteries. It doesn’t absorb, reflect or emit light, so we can’t see it. But its presence is implied by the gravitational effects it appears to have on galaxies.

Although dark matter makes up about 85% of the cosmos, scientists know very little about its fundamental nature.

Theories abound, and research by Clemson University postdoctoral fellow Alex McDaniel provides some of the most stringent constraints on the nature of dark matter yet. His research also reveals a small hint of a signal that if real, could be confirmed sometime in the next decade or so.

The work is published in the journal Physical Review D.

“With data collection and new discoveries in the future, thi...
