Universe Today 18 Oct 2019, 18:23 UTC The universe bathes in a sea of light, from the blue-white flickering of young stars to the deep red glow of hydrogen clouds. Beyond the colors seen by human eyes, there are flashes of x-rays and gamma rays, powerful bursts of radio, and the faint, ever-present glow of the cosmic microwave background. The cosmos is filled with colors seen and unseen, ancient and new. But of all these, there was one color that appeared before all the others, the first color of the universe.
Astrobiology Magazine 18 Oct 2019, 15:29 UTC Comets screaming through the atmosphere of early Earth at tens of thousands of miles per hour likely contained measurable amounts of protein-forming amino acids. Upon impact, these amino acids self-assembled into significantly larger nitrogen-containing aromatic structures that are likely constituents of polymeric biomaterials.
NASA Space Station Blog 18 Oct 2019, 11:41 UTC Two NASA astronauts switched their spacesuits to battery power this morning at 7:38 a.m. EDT. Expedition 61 Flight Engineers Christina Koch and Jessica Meir are venturing out into the vacuum of space to replace a failed power controller, also known as a battery charge-discharge unit (BCDU). The BCDU regulates the charge to the batteries that collect and distribute solar power to the orbiting lab’s systems.
SciTech Daily 18 Oct 2019, 07:29 UTC When astronomers use the NASA/ESA Hubble Space Telescope to study the deep sky, asteroids from our Solar System can leave their marks on the captured pictures of far-away galaxies or nebulae. But rather than be annoyed at the imprinted trails in Hubble images, astronomers realized they could use them to find out more about the asteroids themselves.
SciTech Daily 18 Oct 2019, 07:16 UTC What does a gestating baby planet look like? New research in Nature by a team including Carnegie’s Jaehan Bae investigated the effects of three planets in the process of forming around a young star, revealing the source of their atmospheres.
Parabolic Arc 17 Oct 2019, 18:48 UTC NASA will host a media teleconference at 3:30 p.m. EDT Friday, Oct. 18, to discuss recommendations presented by the Planetary Protection Independent Review Board (PPIRB), established in June 2019 by Thomas Zurbuchen, associate administrator for the agency’s Science Mission Directorate.
The Planetary Society Blog 17 Oct 2019, 15:59 UTC It took 10 years to transform The Planetary Society's crowdfunded LightSail 2 mission from an idea on the drawing board into a space mission. Dozens of people worked on the project over the years, backed by funding from more than 50,000 Planetary Society members, private citizens, foundations, and corporate partners.
