A pair of astronauts tried on U.S. spacesuits this morning ahead of a spacewalk next week. Afterward, the crew explored heart cells, fluid pressure in the head and the eyes and the composition of meteors.
NASA astronauts Jeff Williams and Kate Rubins are due to work outside the International Space Station on Aug. 19 for 6.5 hours. The duo tried on the spacesuits today they will wear during the spacewalk to complete the installation of the first of two International Docking Adapters to the Har [...]
The small smattering of bright blue stars in the upper left of this vast new 615 megapixel ESO image is the perfect cosmic laboratory in which to study the life and death of stars. Known as Messier 18 this star cluster contains stars that formed together from the same massive cloud of gas and dust. This image, which also features red clouds of glowing hydrogen and dark filaments of dust, was captured by the VLT Survey Telescope (VST) located at ESO’s Paranal Observatory in Chile.

Two cosmic structures show evidence for a remarkable change in behavior of a supermassive black hole in a distant galaxy. Using data from NASA’s Chandra X-ray Observatory and other telescopes, astronomers are piecing together clues from a cosmic “blob” and a gas bubble that could be a new way to probe the past activity of a giant black hole and its effect on its host galaxy.
The Green Blob, a renowned cosmic structure also called “Hanny’s Voorwerp” (which means “Hanny’s object [...]
NASA's Cassini spacecraft has found deep, steep-sided canyons on Saturn's moon Titan that are flooded with liquid hydrocarbons. The finding represents the first direct evidence of the presence of liquid-filled channels on Titan, as well as the first observation of canyons hundreds of meters deep.
A new paper in the journal Geophysical Research Letters describes how scientists analyzed Cassini data from a close pass the spacecraft made over Titan in May 2013. During the flyby, Cassini's radar [...]
NASA has selected six U.S. companies to help advance the Journey to Mars by developing ground prototypes and concepts for deep space habitats.
Through the public-private partnerships enabled by the Next Space Technologies for Exploration Partnerships-2 (NextSTEP-2) Broad Agency Announcement, Appendix A, NASA and industry partners will expand commercial development of space in low-Earth orbit while also improving deep space exploration capabilities to support more extensive human spaceflight m [...]
Will either of these galaxies survive? In what might be dubbed as a semi-final round in a galactic elimination tournament, the two spirals of NGC 7318 are colliding. The featured picture was created from images taken by the Hubble Space Telescope. When galaxies crash into each other, many things may happen including gravitational distortion, gas condensing to produce new episodes of star formation, and ultimately the two galaxies combining into one.
Since these two galaxies are part of Steph [...]
The Expedition 48 crew continued more eye exams and ongoing research to understand how microgravity shifts body fluids toward the upper body. Two NASA astronauts also checked out U.S. spacesuit safety gear and tools.
All six crew members participated in variety of eye exams throughout the day. Some of the eye checks also coincided with the Fluid Shifts study. That research observes how fluid pressure in space affects a crew member’s head and eyes, possibly affecting vision.
Commander Jef [...]
