Our Hubble Space Telescope finds big surprise in teeny tiny galaxy: A supermassive black hole with a mass 21 million times our sun. The black hole is five times the mass of the one at the center of our Milky Way galaxy. It is inside one of the densest galaxies known to date -- the M60-UCD1 dwarf galaxy that crams 140 million stars within a diameter of about 300 light-years, which is only 1/500th of our galaxy’s diameter. If you lived inside this dwarf galaxy, the night sky would dazzle with at least 1 million stars visible to the naked eye. Our nighttime sky as seen from Earth’s surface shows 4,000 stars. This is an artist's view of M60-UCD1 black hole. Image Credit: NASA, ESA, STScI-RCC14-41a #nasa #space #galaxy #milkyway #blackhole #astronomy #stars #hubble #hst #telescope #science

The last supermoon – in pictures

This full moon marks the third in a trilogy of supermoons this summer. July and August’s full moons both fell during the moon’s perigee – when it was at the closest point in its orbit to Earth. It is also a harvest moon, which rises around the same time that the sun sets, giving the moon a …

Here's another look at the summer sun and solar flare on Aug. 24, 2014. The sun emitted a mid-level solar flare, peaking at 8:16 a.m. EDT on Aug. 24. NASA's Solar Dynamics Observatory captured images of the flare, which erupted on the left side of the sun. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel. This flare is classified as an M5 flare. M-class flares are ten times less powerful than the most intense flares, called X-class flares.
