What happens when a black hole devours a star? Many details remain unknown, but recent observations are providing new clues. In 2014, a powerful explosion was recorded by the ground-based robotic telescopes of the All Sky Automated Survey for SuperNovae (ASAS-SN) project, and followed up by instruments including NASA's Earth-orbiting Swift satellite.
Computer modeling of these emissions fit a star being ripped apart by a distant supermassive black hole. The results of such a collision are por [...]
The Space Show, hosted by David Livingston at www.TheSpaceShow.com, will have the following guests this week:
1. Monday, March 27, 2017, 2-3:30 PM PDT (21-22:30 GMT)
"America Needs a US Space Corps!" discussed with Dr. M.V. "Coyote" Smith, Col, USAF-RET.
Colonel M.V. Smith is a PhD student of strategic studies in the Politics and International Relations Department at the University of Reading in the United Kingdom. Most recently he served as the Chief of “Dream Works,” which is the Futu [...]
Is this an alien? Probably not, but of all the animals on Earth, the tardigrade might be the best candidate. That's because tardigrades are known to be able to go for decades without food or water, to survive temperatures from near absolute zero to well above the boiling point of water, to survive pressures from near zero to well above that on ocean floors, and to survive direct exposure to dangerous radiations. The far-ranging survivability of these extremophiles was tested in 2011 outside an o [...]
Approaching opposition early next month, Jupiter is offering some of its best telescopic views from planet Earth. On March 17, this impressively sharp image of the solar system's ruling gas giant was taken from a remote observatory in Chile. Bounded by planet girdling winds, familiar dark belts and light zones span the giant planet spotted with rotating oval storms.
The solar system's largest moon Ganymede is above and left in the frame, its shadow seen in transit across the northern Jovian [...]
Expedition 50 Commander Shane Kimbrough of NASA and Flight Engineer Thomas Pesquet of ESA (European Space Agency concluded their spacewalk at 1:58 p.m. EDT. During the spacewalk, which lasted just over six-and-a-half hours, the two astronauts successfully disconnected cables and electrical connections on the Pressurized Mating Adapter-3 to prepare for its robotic move Sunday, March 26.
The PMA-3 provides the pressurized interface between the station modules and the International Docking Adapt [...]
Astronomers have uncovered a supermassive black hole that has been propelled out of the center of a distant galaxy by what could be the awesome power of gravitational waves.
Though there have been several other suspected, similarly booted black holes elsewhere, none has been confirmed so far. Astronomers think this object, detected by NASA's Hubble Space Telescope, is a very strong case. Weighing more than 1 billion suns, the rogue black hole is the most massive black hole ever detected to ha [...]
By harnessing the extreme sensitivity of the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have directly observed a pair of Milky Way-like galaxies seen when the universe was only eight percent of its current age. These progenitors of today’s giant spiral galaxies are surrounded by "super halos" of hydrogen gas that extend many tens of thousands of light-years beyond their dusty, star-filled disks.
Astronomers initially detected these galaxies by studying the intense ligh [...]
