The missing dark matter in certain galaxies can be explained by the effects of tidal disruption: the gravity forces of a neighboring massive galaxy, literally tearing the smaller galaxy apart. #darkmatter
While appearing as a delicate and light veil draped across the sky, this image from the NASA/ESA Hubble Space Telescope actually depicts a small section of the Cygnus supernova blast wave, located around 2600 light-years away. #hubble #CygnusLoop
Since it launched in 1990, the Hubble Space Telescope has snapped more than a million images and changed the way we see the universe, literally. Here’s why the Hubble images and the technology are so unique. #hubbletelescope
New measurements from NASA’s Hubble Space Telescope confirm that the Universe is expanding about 9% faster than expected based on its trajectory seen shortly after the big bang, astronomers say. #universe
One possibility to explain the speed in which the universe is expanding – is that dark energy, already known to be accelerating the cosmos, maybe shoving galaxies away from each other with even greater — or growing — strength. This means that the acceleration itself might not have a constant value in the universe but changes over time in the universe. #theuniverse
Astronomers have discovered a stunning set of 39 massive galaxies
In the hunt for life on other worlds, astronomers scour over planets that are light-years away. They need ways to identify life from afar—but what counts as good evidence? #nasa
NGC 2903 is a galaxy located about 30 million light-years away in the constellation of Leo (the Lion) and was studied as part of a Hubble survey of the central regions of roughly 145 nearby disk galaxies.
Albert Einstein predicted that whenever light from a distant star passes by a closer object, gravity acts as a kind of magnifying lens, brightening and bending the distant starlight. Yet, in a 1936 article in the journal Science, he added that because stars are so far apart “there is no hope of observing this phenomenon directly.” Until now!
Sept. 26: NASA Sets to Release Details of ‘Surprising Activity’ on Europa, Many Speculate Alien Life
According to NASA, it will hold a teleconference on Monday, Sept. 26, 2016, to present new findings From images of Europa, one of the largest of Jupiter’s 67 known moons
The Hubble Space Telescope is known for its dazzling images of cosmic phenomena, but it didn’t exactly start that way. Its first ever image, captured 25 years ago today, is decidedly less exciting. This is HD96755, a part of star cluster NGC 3532, about 1,300 light years away. It underwhelmed people back then, too.
The Hubble Space Telescope has taken a fresh look at the iconic Pillars of Creation in the Eagle Nebula 6,500 light-years from Earth, revealing the most detailed view yet of a feature Hubble originally discovered 20 years ago. The new image was taken to commemorate Hubble’s 25th anniversary in 2015.
