Ice in a planetary cauldron

With temperatures in excess of 800 F, Mercury is one of the last places in the solar system you’d expect to find ice. But when NASA’s Messenger spacecraft transmitted its first optical images of the closest planets to the sun, that’s exactly what scientists discovered. Mercury sits about 36 million miles from the sun, which is roughly 57 million miles […]

How the moon was made

How the moon was made

People always wonder how the moon was made. The birth of the planets 4.5 billion years ago was extremely violent. They grew to full size by absorbing rival planet embryos in a series of titanic collisions—one of which probably gave Earth its moon (below). The moon’s large size, low density, and other features suggest that it emerged from an explosion […]

Galactic turmoil ahead

The Milky Way and its closest neighbor, the Andromeda galaxy, are on course for “ a head-on collision,” says astronomer Roeland van der Marel of the Space Telescope Science Institute. But no need for precautions because the crash won’t happen for another 4 billion years. Researchers have long known that Andromeda, currently some 2.5 million light-years away, is moving toward […]

The sun takes a rare hiatus

Sunspot activity may be entering a lull for the first time in almost 400 years, offering scientists a rare chance to gauge how solar conditions affect Earth’s climate. “This is highly unusual and unexpected” says Frank Hill, a researcher at the National Solar Observatory. Three new NSO studies suggest that the sun’s fluctuating magnetic field may soon become too weak […]

Gene editing: A step toward ‘designer babies’

Gene editing

“Turns out the rumors are true,”. Word has spread through the scientific community that “researchers in China have successfully edited the genomes of human embryos.” Those rumors were confirmed when a team from Sun Yat-sen University published laboratory results revealing that they had crossed an ethical red line, using a gene editing tool on embryos to modify the gene responsible […]
