Hubble’s Vivid New Images of Jupiter’s Polar Aurora –“Larger than Earth”

Astronomers are using the NASA/ESA Hubble Space Telescope to study auroras — stunning light shows in a planet’s atmosphere — on the poles of the largest planet in the Solar System, Jupiter. This observation program is supported by measurements made by NASA’s Juno spacecraft, currently on its way to Jupiter. Jupiter’s auroras were first discovered by the Voyager 1 spacecraft in 1979. A thin ring of light on Jupiter’s nightside looked like a stretched-out version of our own auroras on Earth. Only later on was it discovered that the auroras were best visible using the ultraviolet capabilities of the NASA/ESA Hubble Space Telescope.

“Rogue Monsters of the Cosmos” –Supermassive Black Holes Detected Ejected from Their Galaxy

The central regions of many glittering galaxies, our own Milky Way included, harbor cores of impenetrable darkness — black holes with masses equivalent to millions, or even billions, of suns. What’s more, these supermassive black holes and their host galaxies appear to develop together, or “co-evolve.” Theory predicts that as galaxies collide and merge, growing ever more massive.

“Red dwarfs – the dim bulbs of the cosmos – have received scant attention by SETI scientists in the past,” SETI Institute engineer Jon Richard said last week in a news release announcing the initiative. “That’s because researchers made the seemingly reasonable assumption that other intelligent species would be on planets orbiting stars similar to the sun.”

Stealth Black Holes Detected Throughout Milky Way –“Closer to Earth Than We Thought”

By combining data from Chandra and several other telescopes, astronomers have identified the true nature of an unusual source in the Milky Way galaxy. This discovery implies that there could be a much larger number of black holes in the Galaxy that have previously been unaccounted for. For about two decades, astronomers have known about an object called VLA J213002.08+120904 (VLA J2130+12 for short). Although it is close to the line of sight to the globular cluster M15, most astronomers had thought that this source of bright radio waves was probably a distant galaxy.

“The dips found by Kepler are real. Something seems to be transiting in front of this star and we still have no idea what it is!” confirms German astronomer Michael Hippke. Even if aliens are not involved, Tabby’s star remains “the most mysterious star in the universe” as Yale astronomer Tabetha Boyajian described it in a TED talk she gave last February.
