The Smallest Black Hole in the Universe (Synopsis)

A binary system containing a stellar-mass black hole called IGR J17091. The strong gravity of the black hole, on the left, is pulling gas away from a companion star on the right. This gas forms a disk of hot gas around the black hole, and the wind is driven off this disk(Credit: NASA/CXC/M.Weiss)

NASA: Sun’s corona much larger than previously thought

Scientists used these observations of the sun's atmosphere (the bright light of the sun itself is blocked by the black circle at the middle) from NASA's Solar Terrestrial Relations Observatory on Aug. 5, 2007, to define the outer limits of the solar atmosphere, the corona.

Science and spacewalks on Space Station

This might look like a routine scientific experiment, but you’re actually looking at European Space Agency astronaut Alexander Gerst as he sets fire to samples of various solids aboard the International Space Station to see how they burn. This man truly has a wonderful job. (Credit: ESA)

New Observatory Takes Highest-Energy Particle Research to New Heights

As cosmic-ray particles are accelerated by a black hole in this artist's interpretation, they stream toward Earth as very-high-energy gamma-rays. Upon hitting the atmosphere, they produce a shower of particles that rain down on Earth. Most of these particles run out of energy before they hit sea level.

Swiftly Moving Gas Streamer Eclipses Supermassive Black Hole

This is an illustration of the physical, spatial and temporal picture for the outflows emanating from the vicinity of the super massive black hole in the galaxy NGC 5548. The behavior of the emission source in five epochs is shown along the time axis. The obscurer is situated at roughly 0.03 light years (0.01 parsecs) from the emission source and is only seen in 2011 and 2013 (it is much stronger in 2013). Outflow component 1 shows the most dramatic changes in its absorption troughs. Different observed ionic species are represented as colored zones within the absorbers.
