Red dwarf planets may be safe from superflares

Planets orbiting red dwarf stars could still be habitable despite superflares of intense radiation coming from the stars. It all has to do with the direction the flares are erupting in.

Are Mars’ subsurface lakes really lakes?

Researchers suggest that Mars' subsurface lakes beneath the south polar ice cap may not actually be lakes after all. The first presumed lakes were discovered in 2018 and 2020, and now radar images from Mars Express reveal even more. But many of them are in locations too cold for even salty water to stay liquid.

An inner solar system much like ours, 35 light-years away

Astronomers using the Very Large Telescope have been studying a distant exoplanet with an inner solar system much like ours.

Neutron-star mountains are tiny (but you can’t climb ’em)

Researchers in the UK have found that neutron-star mountains are less than a millimeter tall. These dense, dead stars are nearly perfectly smooth spheres.

1st moon-forming disk around an exoplanet

Astronomers have found solid evidence for a moon-forming disk around a distant exoplanet. It provides new clues as to how moons and planets form.

9 weird transients from 1950 still unexplained

Astronomers in Sweden want to solve the mystery of 9 weird transients, glimpsed in a photographic plate acquired at Palomar Observatory in 1950.

Cracked surface of Venus behaves like sea ice

Venus' cracked surface suggests a moveable crust for this nearby world, and suggests the planet might still be geologically active today.

The awesome beauty of the Eagle Nebula

The Eagle Nebula - aka Messier 16 or M16 - is home to several well-known cosmic structures, including the stunning Pillars of Creation and Stellar Spire.

Moons of rogue planets could have water and life

A new study from scientists at LMU in Germany says that there could be enough heat and liquid water on moons of rogue planets - free-floating worlds with no suns - to support life. Cosmic rays could drive processes such as photosynthesis, instead of direct sunlight.

Are Earth-like biospheres rare?

A new study from researchers at the University of Naples in Italy suggests that highly-evolved, Earth-like biospheres may be rare on exoplanets. Many stars either don't emit enough energy for life to develop past the basic photosynthesis stage or don't live long enough for life to evolve on any planets that may otherwise be suitable.
