Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered nine new "hot Jupiter" exoplanets. One of the newly detected alien worlds is almost four times more massive than ...
Astronomers have discovered a pair of exoplanets orbiting an M dwarf star, one of which is the coldest M dwarf planet found by the TESS satellite observatory, making it accessible for follow-up studies of its atmosphere. ...
New research from a Western University postdoctoral fellow shows the early lunar crust, which makes up the surface of the moon, was considerably enriched in water more than 4 billion years ago, counter to previously held ...

Using the James Webb Space Telescope (JWST), astronomers have investigated a nearby sub-Earth exoplanet known as Gliese 367 b. The obtained results indicate that this alien world is dark, hot and lacks a detectable atmosphere. ...
Titan's "magic islands" are likely floating chunks of porous, frozen organic solids, a new study finds, pivoting from previous work suggesting they were gas bubbles. The study was published in Geophysical Research Letters.

Giant-impact driven redox processes in the atmosphere and magma ocean may have played crucial roles during the evolution of the Earth. However, the absence of rock records from the time or era makes it challenging to understand ...
A vast, flat, "featureless" plain on Mars surprised researchers by revealing a much more tumultuous geologic past than expected, according to a study led by researchers at the University of Arizona. Enormous amounts of lava ...
