Hubble's Vivid New Images of Jupiter's Polar Aurora --"Larger than Earth"

 

 

118728_web


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.

Scientists Shift Search for Alien Technological Civilizations to Ancient Red-Dwarf Stars --"Twice Age of Earth"

“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.”

Sorry NASA, but it turns out that a 1917 image on an astronomical glass plate from the Carnegie Institute Observatories' collection shows the first-ever evidence of a planetary system beyond our own Sun. This unexpected find was recognized in the process of researching an article about planetary systems surrounding white dwarf stars in New Astronomy Reviews.

"Recycling the Hidden Universe" --Forging Cosmic Dust Into Stars

The Universe is becoming gradually cleaner as more and more cosmic dust is being mopped up by the formation of stars within galaxies, an international team of astronomers has revealed. Peering back 12 billion years using the Herschel space telescope to produce far-infrared images of the sky, the team led by researchers at Cardiff University has been able to observe the very early formation of galaxies and compare them to galaxies that have formed much more recently.

"Yes, Robots Dream!" --RobERt: Deep Belief Neural Network To Search for Habitable Planets

"Robots really do dream. We can ask RobERt to dream up what he thinks a water spectrum will look like, and he's proved very accurate," says Ingo Waldmann of University College London. "This dreaming ability has been very useful when trying to identify features in incomplete data. RobERt can use his dream state to fill in the gaps."

"We Can Now Send Light Signals Across the Cosmos" --Revolutionizes Possible Alien Contact (Wednesday's Most Popular)

“Suppose there is a civilization like ours and suppose — unlike us, who are skittish about broadcasting our presence — they think it’s important to be a beacon, an interstellar or extragalactic lighthouse of sorts,” says University of California  Santa Barbara physicist, Philip Lubin.. “There is a photonics revolution going on on Earth that enables this specific kind of transmission of information via visible or near-infrared light of high intensity."

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.

Precursor to Life? --"Ring of Organic Molecules Discovered Around Newborn Star"

Astronomers have long known that organic molecules form in diffuse gas clouds floating between stars. It is thought that as the Solar System formed 4.6 billion years ago, some of these organic molecules were transported from interstellar space to the planet forming disk. Later, these molecules played important roles in the chemical evolution resulting in the emergence of life on the Earth.

A Southwest Research Institute-led team has discovered an elusive, dark moon orbiting Makemake, one of the "big four" dwarf planets populating the Kuiper Belt region at the edge of our solar system. The findings are detailed in the paper "Discovery of a Makemakean Moon," published in the June 27 issue of Astrophysical Journal Letters.
