Five decades of common knowledge about the Milky Way and Andromeda galaxies has been turned on its head, with astronomers at the International Centre for Radio Astronomy Research (ICRAR) discovering that our nearest galactic neighbor, rather than being two to three times bigger, is roughly the same size as the galaxy we call home...Continue Reading Astronomers bring Andromeda down to sizeCate
The supermassive black holes lurking at the center of galaxies have been known to chow down on anything unlucky enough to pass too close, but the opportunity to see that in action rarely occurs at the Milky Way's quiet core. Now, astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) observatory in Chile have imaged a very active black hole at the center of spiral galaxy M7
Incredibly powerful but gone in a flash, mysterious signals known as Fast Radio Bursts (FRBs) are regularly detected in all corners of the sky. A repeating signal known as FRB 121102 was already the weirdest one out there, but now an international team of astronomers has found that this oddball is even odder than previously thought. The radio waves from FRB 121102 are being "twisted" to an ex
An international team of astronomers has completed the deepest spectroscopic survey of the early universe ever undertaken, collecting data on 1,600 galaxies, and discovering 72 previously unknown candidate galaxies. The scientists observed a tiny patch of sky that had before served as the subject for the now-famous 2004 Hubble Ultra Deep Field images (HUDF)...Continue Reading Astronomers peer
We've managed to send spacecraft out into the vast realm beyond our solar system, and now it looks as if the Galaxy is repaying the compliment. An object originating from outside the Solar System has been detected passing through the Sun's real estate. Temporarily designated as A/2017 U1, the extrasolar asteroid or comet was recorded after approaching from interstellar space and heading out a
The Moon isn't the only traveling buddy keeping the Earth company on its journey around the Sun. Occasionally an asteroid will get caught in a gravitational dance with our home for a few years or so, before disappearing into space again. Last year astronomers discovered one of the most stable of these "quasi-satellites", and now they've peered closer to get a better understanding of what it i
The Moon seems like a pretty barren place, but studies in 2009 revealed traces of water in the lunar soil. Now, scientists from Brown University have used data gathered from NASA's Moon Mineralogy Mapper instrument to construct a detailed map of where water can be found on the Moon – and it turns out it's more widespread than previously thought...Continue Reading Astronomers map out the Moon'
In July 2015, the New Horizons probe zipped past Pluto, and images and information gathered during the historic flyby are still being processed and studied. Now, the International Astronomical Union (IAU) has officially named 14 features on the dwarf planet's surface. The various mountains, ridges and valleys have all been given titles that honor influential astronomers and spacecraft, or con
An international team of astronomers has discovered the smallest ever star to date – a tiny red dwarf only slightly larger than the planet Saturn. Known as EBLM J0555-57Ab, it sits roughly 600 light years from Earth, and is so small that it was discovered using a technique ordinarily used for hunting exoplanets...Continue Reading Astronomers discover tiny, planet-sized starCategory: SpaceTags
