This is the first multiple discovery of its kind, and such an abundance of this type of galaxy defies current models of the universe.
Previously unknown webs of stars are more spectacular than our own, say researchers.
The world’s largest telescope in the Canary Islands of Spain has an aperture, or opening through which light comes through, of 409 inches.
Don’t worry, this was a planned end for a tiny satellite that has been a huge success.
At 14:08 UTC on 31 July, Longjiang-2, also known as DSLWP-B, passed behind the Moon for the last time. Half an hour later, with an absence of new signals to indicate a reappearance, it was clear that the Moon had lost an orbiter and gained a new crater on its far side. According to a prediction by Daniel Estévez, the 50-centimeter-tall, 47-kilogram DSLWP-B satellite impacted at 14:20 UTC.
Not to worry—this was a planned measure to prevent potential collisions or debris for future missions. A maneuver performed 24 January lowered the periapsis of the satellite’s lunar orbit by about 500 kilometers, with orbital perturbations over time seeing the satellite impacting the Moon Wednesday after 432 days in lunar orbit.
Seven years. 13 miles. 22 samples. NASA’s Curiosity Mars Rover has come a long way since touching down on the Red Planet seven years ago. See for yourself: https://www.nasa.gov/feature/jpl/new-finds-for-mars-rover-se…er-landing
NASA’s Curiosity rover has come a long way since touching down on Mars seven years ago. It has traveled a total of 13 miles (21 kilometers) and ascended 1,207 feet (368 meters) to its current location. Along the way, Curiosity discovered Mars had the conditions to support microbial life in the ancient past, among other things.

Physicists Sergio Ferrara, Dan Freedman, and Peter van Nieuwenhuizen will split a $3 million Breakthrough Prize for their theory of supergravity, which drives much of today’s physics research toward our understanding of the universe.
The Breakthrough Prize is an annual award to recognize groundbreaking science, funded by Russian-Israeli billionaire Yuri Milner. Though Breakthrough Prizes are awarded annually, “special” Breakthrough Prizes can be awarded any time and need not honor recent work. In fact, the researchers behind today’s award thought they’d missed the chance to win it.
University of Arizona Project Nautilus aims to create a space telescope that can survey transiting exo-earths for biosignatures 1000 light years away.
It’s a riddle of cosmic proportions: how can the universe contain stars older than itself?
That’s the conundrum now facing astronomers trying to establish the age of the universe – and its resolution could spark a scientific revolution.
At an international conference held in California last month, there was hope a resolution might be found. Instead, the latest findings only confirmed suspicions there is something fundamentally wrong with current ideas of how the universe works.
The photos have stood the test of time: A spacesuit-clad Apollo astronaut stands proudly next to a red-white-and-blue American flag on the moon, his national trophy saying: “The United States was here.”
Unfortunately, the six flags planted on the lunar surface from 1969 through 1972 haven’t fared so well.
Images taken by NASA’s Lunar Reconnaissance Orbiter in 2012 showed that at least five out six flags were still standing. However, scientists think decades’ worth of brilliant sunlight have bleached away their emblematic colors.
