NASA's Webb Telescope will study our solar system's 'ocean worlds'

more »
NASA's James Webb Space Telescope will use its infrared capabilities to study the "ocean worlds" of Jupiter's moon Europa and Saturn's moon Enceladus, adding to observations previously made by NASA's Galileo and Cassini orbiters. The Webb telescope's observations could also help guide future missions to the icy moons.

Phoenicid meteor shower from dead comet arises again after 58 years

more »
Astronomers have observed the elusive 'Phoenicid meteor shower' and have determined that it was spawned by the now vanished Comet Blanpain. They also found that Comet Blanpain was active, though only weakly, in the early 20th Century. This is the first time that researchers could determine the activity of a comet by observing its associated meteor shower. These results are important for understanding the evolution of minor bodies in the Solar System.

Exploring the ground truth: NASA's twin study investigates metabolites

more »
Researchers are integrating multi-omics data for NASA's Twins Study and comparing all the metabolites in retired twin astronauts Scott and Mark Kelly. Experts saw a number of Scott's metabolites increase in levels when he went to space and when he returned to Earth some of those stayed elevated. By integrating data from other Twins Study investigations, they hope they can determine the cause of this elevation.

The Eagle and The Swan

more »
The Eagle Nebula and the Swan Nebula span this broad starscape, a telescopic view toward the Sagittarius spiral arm and the center of our Milky Way galaxy. The Eagle, also known as M16, is at top and M17, the Swan, at bottom of the frame showing the cosmic clouds as brighter regions of active star-formation. They lie along the spiral arm suffused with reddish emission charactistic of atomic hydrogen gas, and dusty dark nebulae. M17, also called the Omega Nebula, is about 5500 light-years away, while M16 is some 6500 light-years distant. The center of both nebulae are locations of well-known close-up images of star formation from the Hubble Space Telescope. In this mosaic image that extends about 3 degrees across the sky, narrowband, high-resultion image data has been used to enhance the central regions of the Eagle and Swan. The extended wings of the Eagle Nebula spread almost 120 light-years. The Swan is over 30 light-years across.
