Astronomers use giant galaxy cluster as X-ray magnifying lens

Science Daily Astronomy - 5 hours 26 min ago
Astronomers have used a massive cluster of galaxies as an X-ray magnifying glass to peer back in time, to nearly 9.4 billion years ago. In the process, they spotted a tiny dwarf galaxy in its very first, high-energy stages of star formation.

Ice on lunar south pole may have more than one source

Science Daily Astronomy - Thu, 2019-10-10 13:57
New research sheds light on the ages of ice deposits reported in the area of the Moon's south pole -- information that could help identify the sources of the deposits and help in planning future human exploration.

Milky Way raids intergalactic 'bank accounts'

Science Daily Astronomy - Thu, 2019-10-10 12:56
Gas blown out of the Milky Way disk from exploding stars falls back onto the galaxy to form new generations of stars. In an effort to account for this recycling process, astronomers were surprised to find a surplus of incoming gas.

The Milky Way kidnapped several tiny galaxies from its neighbor

Science Daily Astronomy - Thu, 2019-10-10 11:32
A team of astronomers has discovered that several of the small -- or 'dwarf' -- galaxies orbiting the Milky Way were likely stolen from the Large Magellanic Cloud, including several ultrafaint dwarfs, but also relatively bright and well-known satellite galaxies, such as Carina and Fornax.

Pressure runs high at edge of solar system

Science Daily Astronomy - Tue, 2019-10-08 11:59
Out at the boundary of our solar system, pressure runs high. This pressure, the force plasma, magnetic fields and particles like ions, cosmic rays and electrons exert on one another when they flow and collide, was recently measured by scientists in totality for the first time -- and it was found to be greater than expected.
