NASA's Swift Gets a Boost
Teams have successfully established communications with Katalyst Space’s robotic servicing spacecraft LINK, which is designed to raise the orbit of NASA’s Neil Gehrels Swift Observatory to a higher altitude.
Over the next several weeks, Katalyst will perform checkout procedures for LINK, including assessments of its propulsion, sensor, and navigation systems. LINK will then approach Swift and complete a survey of the 21-year-old observatory, before capturing and lifting it over the course of several months.
Euclid View of Milky Way Heart Previews Core Survey by NASA’s Roman
A new look at the heart of our Milky Way galaxy by Euclid, a European Space Agency mission with NASA contributions, overlaps with a region scientists will observe with NASA’s Nancy Grace Roman Space Telescope, launching later this summer.
This sneak peek gives astronomers a major jumpstart on a core Roman survey, helping scientists learn more than they could from either telescope alone.
NASA’s Fermi Mission Uncovers Possible Sibling Supernova Remnants
A new study of two supernova remnants, the debris left behind after stars explode, suggests the explosions came from stellar siblings that once orbited each other.
The first star’s detonation sent its binary companion hurtling through space, and then, after traveling for thousands of years, the surviving star blew up too.
Chandra reveals new look at Messier 94
Messier 94, also known as NGC 3603, is a spiral galaxy with a bright inner circle around it, called a starburst ring, where new stars are forming, perhaps fueled by gas driven in the unique oval-shaped structure.
In this sonification of NGC 4736, the radar-like scan moves clockwise, and the brightness of the sources dictates the volume of the sounds.
