Antarctica ice melt has accelerated by 280% in the last 4 decades

Antarctica ice melt has accelerated by 280% in the last 4 decades

A pair of new studies released on Monday share a same ominous message — that our planet’s ice is melting at an alarming rate, which is bad news for global sea levels. According to a study led by Eric Rignot from the University of California at Irvine, which looked at details of ice and snow…MORE

Our galaxy is due for a catastrophic collision, study says

Our galaxy is due for a catastrophic collision, study says

While astronomers estimate that the Andromeda galaxy will collide with our own Milky Way galaxy 8 billion years from now, they now believe that another collision will happen even sooner. The Large Magellanic Cloud will catastrophically collide with the Milky Way in 2 billion years, according to a study published this month in the Monthly…MORE

Primitive life is possible on nearby exoplanet, scientists say

Primitive life is possible on nearby exoplanet, scientists say

Astronomers believe that recently discovered super-Earth Barnard’s star b, only six light-years away, might be able to support life. Barnard’s star b was only announced in November; it orbits Barnard’s star, the closest solitary star to our sun. This makes it the second closest-known exoplanet to us. Previously, an exoplanet was found orbiting in the…MORE

The oceans are warming faster than scientists thought

The oceans are warming faster than scientists thought

The world’s oceans are warming at an accelerated rate and are much warmer than scientists thought — and things could get a lot worse if nothing is done to stop climate change, according to a new study. The data, published in Thursday’s edition of the journal Science, shows that the oceans have experienced consistent changes…MORE

A second mysterious repeating fast radio burst has been detected in space

A second mysterious repeating fast radio burst has been detected in space

Far outside our Milky Way galaxy, something is causing repeating short bursts of radio waves to be released into space. Scientists have recorded the second repeating fast radio burst to be discovered, according to a study published Wednesday in the journal Nature. The finding was also presented at the 233rd meeting of the American Astronomical…MORE

NASA’s planet-hunter TESS makes first discoveries

NASA’s planet-hunter TESS makes first discoveries

TESS, NASA’s planet-hunting telescope, has found an exoplanet three times the size of Earth only 53 light-years away. It has also discovered a super-Earth and a rocky world, making three exoplanet discoveries in the first three months since it began surveying the sky in July. The nearby exoplanet, HD 21749b, orbits a bright neighboring star…MORE

Citizen scientists discover rare exoplanet

Citizen scientists discover rare exoplanet

Although NASA’s Kepler space telescope ran out of fuel and ended its mission in 2018, citizen scientists have used its data to discover an exoplanet 226 light-years away in the Taurus constellation. The exoplanet, known as K2-288Bb, is about twice the size of Earth and orbits within the habitable zone of its star, meaning liquid…MORE

A partial solar eclipse happens this weekend over Asia

A partial solar eclipse happens this weekend over Asia

A partial solar eclipse will help kick off the new year Sunday as the moon passes between Earth and the sun. But visibility depends on where you live — and clear skies, of course. The partial solar eclipse will be visible after sunrise in Asia in China, in North and South Korea, in Japan, in…MORE
