Two scientists from the University of Nevada Las Vegas have suggested the existence of at least one super-Earth in the early days of the solar system located within the orbit of planet Mercury which ended up being devoured by the Sun.
Falling in love is just like falling in a black hole, time goes slow for you but is the same for everyone else. But what are black holes? And how did they get here?
Billion years ago, galaxies like our Milky Way underwent an era of prolific star formation, churning out stars at a frenzy rate, 30 times faster than they do today.
A powerful solar flare that erupted on the Sun on Wednesday, March 11, 2015, and reached us here on Friday was large enough to effect radio signals all over the western hemisphere. The X-class solar flare was also captured on video by NASA’s Solar Dynamics Observatory.
How a sunset might look like to a human observer if our Sun was replaced by some of the other stars in our galaxy with different sizes and magnitudes, namely: Barnard’s Star, Gliese 581, Tau Ceti, Kepler-23, Alpha Centauri A, Procyon, Sirius, Pollux, Arcturus and Aldebaran. Enjoy this amazing Photo.
Capturing an image more than once per second, SDO (NASA’s Solar Dynamics Observatory) has provided an unprecedentedly clear picture of how massive explosions on the sun grow and erupt ever since its launch on Feb. 11, 2010. In honor of SDO’s fifth anniversary, NASA has released a video showcasing highlights from the last five years of sun watching. Hope you’ll enjoi it.
It’s hard to imagine what life would look like if we were rotating around some star other than the sun. So the Russian Federal Space Agency imagined for us. And it looks awesome. The video above puts different stars at the center of our solar system, envisioning Earth in a very different light. Five different lights, actually.
One of the best things about the Internet is the speed at which it allows information to be shared. Unfortunately, this means all information — even false ones like the news about the six-day darkness that would envelop the world in December.
The sun lies at the heart of the solar system, where it is by far the largest object. It holds 99.8 percent of the solar system’s mass and is roughly 109 times the diameter of the Earth — about one million Earths could fit inside the sun.
