Astronomers Have Caught a Rare And Massive ‘Accretion Burst’ in Our Galaxy

Posted by in categories: cosmology, materials

Here on Earth, we pay quite a lot of attention to the sun. It’s visible to us, after all, and central to our lives. But it is only one of the billions of stars in our galaxy, the Milky Way. It’s also quite small compared to other stars – most are at least eight times more massive.

These massive stars influence the structure, shape and chemical content of a galaxy. And when they have exhausted their hydrogen gas fuel and die, they do so in an explosive event called a supernova. This explosion is sometimes so strong that it triggers the formation of new stars out of materials in the dead star’s surroundings.

But there’s an important gap in our knowledge: astronomers don’t yet fully understand how those original massive stars themselves are initially formed. So far, observations have only yielded some pieces of the puzzle.

Spacewalk to Repair Alpha Magnetic Spectrometer Outside International Space Station on Jan. 25, 2020

Posted by in categories: cosmology, electronics

Live Spacewalk: Watch as astronauts complete the intricate process of repairing the Alpha Magnetic Spectrometer (AMS), a dark matter and antimatter detector outside the International Space Station.

On Sat., Jan. 25 at 6:50 a.m. EST, tune in for a live spacewalk as Luca Parmitano of the European Space Agency (ESA) and Andrew Morgan of NASA perform the fourth and final spacewalk to repair AMS, which has far outlived its planned three-year lifespan. In addition to revitalizing an important piece of scientific equipment, the process of creating the tools and procedures for these spacewalks is preparing teams for the types of spacewalks that may be required on Moon and Mars missions.

Gravitational wave echoes may confirm Stephen Hawking’s hypothesis of quantum black holes

Posted by in categories: cosmology, quantum physics

Echoes in gravitational wave signals suggest that the event horizon of a black hole may be more complicated than scientists currently think.

Research from the University of Waterloo reports the first tentative detection of these echoes, caused by a microscopic quantum “fuzz” that surrounds newly formed .

Gravitational waves are ripples in the fabric of space-time, caused by the collision of massive, compact objects in space, such as black holes or .

Could Our Universe Be 2-Dimensional? Black Holes Offer A Clue

Posted by in category: cosmology

When you throw something into a black hole, its information seems to disappear. This may be a hint that black holes, as well as our entire universe, is 2-dimensional.
