There may be as many as one Earth-like planet for every five Sun-like stars in the Milky way Galaxy, according to new estimates by University of British Columbia astronomers using data from NASAs Kepler mission. To be considered Earth-like, a …
Breakthrough measurements of exoplanet Proxima B were made with radial velocity measurements of unprecedented precision using ESPRESSO, the Swiss-manufactured spectrograph the most accurate currently in operation which is installed on the Very Large Telescope in Chile. Proxima b …
1. Chandra X-Ray Space Telescope – Can Black Hole Tidal Disruptions Leave Remnants? 2. Cosmoquest – A star that had a brush with a giant black hole and lived to tell the tale through exclamations of X-rays 3. The Hill …
A new design could enable affordable exploration of Venus and other harsh environments. The Venus surface temperatures near 460°C and pressures of 93 bar have made long-duration surface missions infeasible. The atmosphere is also caustic and has a dense cloud …
Hbar Technologies looks at using Breakthrough Starshot laser acceleration to reach Proxima Centauri and then use antimatter propulsion to decelerate. This would not be a flyby mission where a mission would pass through the solar system at 10% of the …
The Carnival of Space 659 is up at Urban Astronomer. Universe Today Are the Gaps in These Disks Caused by Planets? Above – This is the sharpest image ever taken by ALMA sharper than is routinely achieved in visible …
Researchers used a highly sensitive technique to examine 16 samples from two different meteorites to find new superconducting alloys. One meteorite formed in the iron core of an asteroid and one flung off a planets surface by a collision. Above …
Nuclear physicists at the University of York are putting forward a new candidate for dark matter a particle they recently discovered called the d-star hexaquark. Up to 80% of the Universe could be dark matter, but despite many decades …
The Carnival of Space 651 is up at Urban Astronomer. Universe Today – Did Neutrinos Stop The Early Universe From Annihilating Itself? Soon after matter and antimatter appeared in the cosmos, the universe underwent a phase change where more antimatter …
The Palermo Technical Impact Hazard Scale for asteroids is a logarithmic scale used by astronomers to rate the potential hazard of impact of a near-earth object (NEO). It combines two types of dataprobability of impact and estimated kinetic yieldinto a …
