Astronomers using NASA s Hubble Space Telescope have traced the locations of five brief, powerful radio blasts to the spiral arms of five distant galaxies.
Called fast radio bursts (FRBs), these extraordinary events generate as much energy in a thousandth of a second as the Sun does in a year. Because these transient radio pulses disappear in much less than the blink of an eye, researchers have had a hard time tracking down where they come from, much less determining what kind of object or objects is causing them. Therefore, most of the time, astronomers don t know exactly where to look. ....

NASA s Hubble Space Telescope is giving astronomers a rare look at a Jupiter-sized, still-forming planet that is feeding off material surrounding a young star.
We just don t know very much about how giant planets grow, said Brendan Bowler of the University of Texas at Austin. This planetary system gives us the first opportunity to witness material falling onto a planet. Our results open up a new area for this research. ....

In celebration of the 31st anniversary of the launching of NASA s Hubble Space Telescope, astronomers aimed the renowned observatory at a brilliant celebrity star, one of the brightest stars seen in our galaxy, surrounded by a glowing halo of gas and dust.
The price for the monster star s opulence is living on the edge. The star, called AG Carinae, is waging a tug-of-war between gravity and radiation to avoid self-destruction. ....
