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.
The tenuous nitrogen atmosphere of the dwarf planet Pluto is predicted to ultimately collapse and freeze over.
But we need to change the law first
Ten years ago, NASA reported a “perfect storm of cosmic rays.” During the year 2009, radiation peppering Earth from deep space reached a 50-year high, registering levels never before seen during the Space Age.
Here’s what a rumbling Red Planet sounds like
Its diameter suggests the black hole is 6.5 billion times the mass of the sun
President Donald Trump recently called for a “Space Force” to defend the United States’ extraterrestrial operations. Russia, China, and India have also beefed up their military capabilities in space. Are we headed for a cosmic conflict?
In 2018, a team of astronomers from the United States and Canada discovered that an ultra-diffuse galaxy called NGC 1052-DF2 (DF2 for short) contains virtually no dark matter. The galaxy is roughly the size of our Milky Way Galaxy, but hosts only 1/200 the number of stars. It lies in the constellation of Cetus, about 65 million light-years away, and is a member of the NGC 1052 group of galaxies. Now, the team reports the discovery of a second galaxy in this class, residing in the same group.
Last week, the Event Horizon Telescope (EHT) released the first-ever image of a black hole’s shadow cast against the hot gas of its accretion disk. That image, of the black hole at the center of galaxy Messier 87 (M87), was front page news all over the world. Soon, the EHT will produce the first movie of that hot gas whirling chaotically around the shadow, said project leaders who spoke Sunday (April 14) here at the April meeting of the American Physical Society.
An independent report concluded that NASA has no chance of sending humans to Mars by 2033, with the earliest such a mission could be flown being the late 2030s.
