Fifty Years of Dark Matter
In the 1970’s Vera Rubin didn’t set out to upend modern cosmology. She was just always curious about the heavens. It started with building a homemade telescope out of cardboard and glass, and it progressed with her becoming the only astronomy undergraduate student at Vasser College, graduating in 1948. She was qualified enough to get into Princeton, except for the fact that she was a woman, and so they wouldn’t let her in. Despite years of discouragement and harassment, she made a name for herself in cosmology, joining the first generation of scientists to piece together the large-scale structure of the universe.
Satellites watch Category 5 Hurricane Melissa ahead of potentially record-breaking landfall in Jamaica
Hurricane Melissa could make a record-breaking landfall in Jamaica, and satellites are monitoring the situation.

See a colossal 'X' and 'V' appear on the moon after sunset tonight
Turn your telescope on the moon at sunset on Oct. 28 to see a colossal "X" and "V" form on the lunar surface as sunlight picks out broken terrain along the terminator.
Many Asteroid Rotations Are Chaotic. A New Model Helps Explain Them.
Asteroids spin. Most of them do so rather slowly, and up until now most theories of asteroid rotation have failed to explain exactly why. A new paper from Wen-Han Zhou at the University of Tokyo and his co-authors might finally be able to fully explain that mystery as well as a few others related to asteroid rotation. Their work was presented at the Joint Meeting of the Europlanet Science Congress and the American Astronomical Society’s Division for Planetary Science in late September and could impact our understanding of how best to defend against a potentially hazardous asteroid.
Watch 2 Russian cosmonauts spacewalk outside the ISS today
Cosmonauts Sergey Ryzhikov and Alexey Zubritsky will conduct a spacewalk outside the International Space Station today (Oct. 28), and you can watch the action live.

Watch live: Sentinel-1D launch on Ariane 6
The Copernicus Sentinel-1 mission is about to get its fourth satellite, with Sentinel-1D now ready for liftoff. Launch will take place with an Ariane 6 rocket from Kourou, French Guiana and live coverage will be shown on Tuesday, 4 November, at 22:02 CET (18:02 at Kourou).
Building Homes Beyond Earth
A new study has reviewed how space habitat designs have evolved from inflatable bubbles to 3D-printed structures built from Martian dust. The research traces how engineers have wrestled with extreme temperatures, the bombmardment of radiation, and the challenge of building on worlds without breathable air, transforming each obstacle into solved problems with innovative ideas and designs that could soon house the first permanent residents of the Moon and Mars.
Spectral Biosignatures of Airborne Microbes in Planetary Atmospheres
Could scientists find life in the clouds of exoplanet atmospheres? This is what a recently submitted manuscript hopes to address as a team of researchers investigated how the biosignatures of microbes could be identified in exoplanet atmospheres and clouds. This study has the potential to help scientists develop new methods for finding life on exoplanets, either as we know it or even as we don’t know it.
SpaceX launches 28 Starlink satellites from California, lands rocket at sea
SpaceX launched yet another batch of its Starlink satellites today (Oct. 27), sending 28 of them up from California's central coast.
Alien Life
The question of whether we are alone in the universe has captivated humanity for centuries. The possibility of alien life, from simple microbial organisms to advanced civilizations, continues to drive scientific inquiry and fuel our collective imagination. This document explores the various facets of the search for extraterrestrial life, from scientific methodologies to philosophical implications.
Scientists discover 3 Earth-size exoplanets that may have double sunsets — like Tatooine in Star Wars
Using NASA's TESS exoplanet hunter, astronomers have discovered a strange arrangement of exoplanets around tight binary stars that shouldn't be.
