“The simple explanation for the Red Planet’s color is that its regolith, or surface material, contains lots of iron oxide — the same compound that gives blood and rust their hue.” However, the more complex answer is that during the formation of the planet, iron, a ...
Astronomers know this because a significant number of stars within globular clusters have very low metallicity, or metal content, which means they were formed before generations of stars had synthesized large quantities of heavy elements and scattered them throughout the cosmos. While globular ...

Supernovas can briefly outshine entiregalaxiesand radiatemore energy than our sunwill in its entire lifetime. They're also the primary source of heavy elements in the universe.According to NASA, supernovas are "the largest explosion that takes place in space." ...
The astronomers were observing these so-called "standard candle" supernovas to attempt to measure the rate of universal expansion — called the Hubble constant. What they found was more distant supernovas that had exploded when the universe was much younger were fainter than expected. ...
it up to my rig this morning and am going to get into approximate focus shortly. Earliest possible astrophotography opportunity is Sunday evening based on the current forecast. Will see if the astronomers curse holds true as things don't look good for the rest of December here in central...
Estimates show that millions of people have been victims of cyberbullying. Sadly, this includes the famous cases where emotional distress caused Tyler Clementi, Izzy Dix, Lisa Marie Zahra, and dozens of other victims to take their own lives. These bullie
