Space exploration

The ULLYSES program studied two types of young stars: super-hot, massive, blue stars and cooler, redder, less massive stars than our Sun. The top panel is a Hubble Space Telescope image of a star-forming region containing massive, young, blue stars in 30 Doradus, the Tarantula Nebula. Located within the Large Magellanic Cloud, this is one of the regions observed by ULLYSES. The bottom panel shows an artist's concept of a cooler, redder, young star that's less massive than our Sun. This type of star is still gathering material from its surrounding, planet-forming disk.

Hubble Telescope’s Ambitious Survey Provides Unprecedented Insights into the Lives of Stars

The drawing on the left depicts Enceladus and its ice-covered ocean, with cracks near the south pole that are believed to penetrate through the icy crust. The middle panel shows where authors believe life could thrive: at the top of the water, in a proposed thin layer (shown yellow) like on Earth’s oceans. The right panel shows that as gas bubbles rise and pop, bacterial cells could get lofted into space with droplets that then become the ice grains that were detected by Cassini.

New Study Reveals Potential for Detecting Life on Icy Moons of Saturn and Jupiter

MIT geologists determined the original orientation of many of the bedrock samples collected on Mars by the Perseverance rover, depicted in this image rendering. The findings can give scientists clues to the conditions in which the rocks originally formed. Credits:Image: NASA/JPL-Caltech

About the size of a baby grand piano, the Coronagraph is designed to block starlight and allow scientists to see the faint light from planets outside our solar system. Credit: NASA/JPL-Caltech

NASA Puts Next-Gen Exoplanet-Imaging Technology to the Test

Young, hot, Earth-sized planet HD 63433d sits close to its star in the constellation Ursa Major, while two neighboring, mini-Neptune-sized planets — identified in 2020 — orbit farther out.

Earth-sized planet discovered in ‘our solar backyard’

Voyager 2/ISS images of Uranus and Neptune released shortly after the Voyager 2 flybys in 1986 and 1989, respectively, compared with a reprocessing of the individual filter images in this study to determine the best estimate of the true colours of these planets.

Failure to launch: Does spaceflight increase men’s risk of erectile dysfunction?

Panchromatic view of MACS0416, a galaxy cluster about 4.3 billion light-years from Earth. The image was created by combining infrared observations from NASA’s James Webb Space Telescope with visible-light data from NASA’s Hubble Space Telescope. The resulting prismatic panorama of blues and reds give clues to the distances of the galaxies.
