A new look at the Large Magellanic Cloud is helping astronomers better understand how groups of stars evolve. (Credit: ESA/NASA)
NASA’s Hubble Space Telescope has taken new observations of
the Large Magellanic Cloud, a small, neighboring galaxy to our Milky Way and
found new insights into the star clusters that live there.
Star clusters are quite common in the universe. If a galaxy
is a cosmic metropolis, star clusters would be like a small town. They form as huge
clouds of gas and ...read more

But it turns out adrenaline might not be what activates our brains' stress reaction after all.
In fact, our bones might be doing more work than ...read more
Astronomers first found Comet C/2019 Q4 on August 30. The past week of observations, including this image taken by the Canada-France-Hawaii Telescope on Hawaii's Big Island, have increased astronomers confidence that the comet started life in another solar system.

A newly discovered comet has astronomers excited. Formally
named C/2019 Q4 (Borisov), the object appears to have come from outside our
solar system. If confirmed, that would make it the seco ...read more

Hurricane Dorian seen from the MODIS imager on Terra, August 31, 2019. NASA.
We seem to now live in an age where people are comfortable ignoring experts, especially those in the sciences.
You may have noticed that Hurricane Dorian didn't hit Alabama. Depending on the circles in which you run, you might think it was a "close call" or a completely mistaken statement that Alabama was ever in any real danger from the hurricane. However, what is clear is that when experts in meteorology -- the ...read more

Cancer therapies often fail to work when tested in clinical trials. As a result, a startling 97 percent of drugs designed for specific cancer treatments do not receive approval from the Food and Drug Administration. Now researchers say they may have figured out part of the reason why.
In a new study out Wednesday in the journal Science Translational Medicine, scientists report many cancer drugs don't work the way their designers assumed the ...read more
Dead seaweed chokes beaches across the Caribbean every year. (Credit: Playa del Carmen/Shutterstock)
(Inside Science) -- In the summer of 2018, thousands of tons of a prolific seaweed called sargassum invaded the pristine beaches of the Caribbean. In Mexico, the turquoise waters and clear, smooth sand of the touristy Mayan Riviera turned into a brown mess. The sight of sargassum -- a type of brown algae -- and its smell scared tourists away, and local ecosystems started to suffer greatly. ...read more

The Milky Way is blowing bubbles. Two giant radio bubbles,
extending out from the galaxy for over 1,400 light years, were just discovered
in X-ray data. Astronomers think the bubbles started forming a few million
years ago due to some type of cataclysmic ...read more
