Purple Earth Bacteria Could Survive On Alien Worlds Say Scientists University of Miami researchers show that extreme alien light could support life of terrestrial bacteria Purple bacteria contain pigments that allow them to use sunlight as their source of energy, hence their color. Small as they are, these microbes can teach us a lot about life on Earth, because they have been around longer than most other organisms on the planet.
Lunar Orbiters Discover Source Of Space Weather Near Earth Solar storms — powerful eruptions of solar material and magnetic fields into interplanetary space — can cause what is known as “space weather” near Earth, resulting in hazards that range from interference with communications systems and GPS errors to extensive power blackouts and the complete failure of critical satellites. Process of magnetic reconnection, which powers the phenomena known as space weather.
Find A “Space Warp” Astronomers Seek Online Volunteers In Search For Space Warps Cosmic needle in a haystack: spotting a space warp (gravitational lens) in an image of thousands of other galaxies is tricky
Comet Factory Discovered, Annotated image from ALMA showing the dust trap in the disc that surrounds the system Oph-IRS 48. The dust trap provides a safe haven for the tiny dust particles in the disc, allowing them to clump together and grow to sizes that allow them to survive on their own. The green area is the dust trap, where the bigger particles accumulate. The size of the orbit of Neptune is shown in the upper left corner to show the scale.
NASA Releases “Alien Invader” Photo From Distant Galaxy The universe is eerie enough without giving us an apparition of a 1980s video game alien attacker. This oddball-looking object is really a mirage created by the gravitational field of a foreground cluster of galaxies warping space and distorting the background images of more distant galaxies.
