Gigantic cloud bounces back to our galaxy

New Hubble telescope observations suggest that a high-velocity gas cloud was launched from the outer regions of our own galaxy around 70 million years ago. Now, the cloud is on a return collision course and is expected to plow into the Milky Way's disk in about 30 million years. Astronomers believe it will ignite a spectacular burst of star formation then.

Globular Clusters Could Nurture Interstellar Civilizations

An ideal place to look for spacefaring civilizations may be within bunches of stars called globular clusters, a study claims—because they’re tightly packed with old stars. The idea is that the stars are within communicating distance of each other, and old enough to host planets that have evolved advanced life forms.

Martian moon could disintreagate to become a ring

Mars’ largest moon is slowly falling toward the planet—but rather than smash into it, the moon will probably disintegrate into bits that will form a ring around Mars, scientists predict. The demise of the moon Phobos will occur in an estimated 20 million to 40 million years, leaving a ring that will last for anywhere from one million to 100 million years, according to the two earth scientists at the University of California, Berkeley.

Astroid mining may become a reality soon

The grizzled asteroid miner is a stock character in science fiction. Now, two recent events—one legal, one technological brought asteroid mining closer to reality, according to experts. The legal step took place when the U.S. Senate’s Commerce, Science and Transportation Committee passed a bill titled H.R. 2262—SPACE Act of 2015.

Comet Loveloy detected dumping alcohol into space

Comet Lovejoy lived up to its name by releasing large amounts of alcohol as well as a type of sugar into space, according to new observations. The finding marks the first time ethyl alcohol, the same type in alcoholic beverages, has been detected in a comet, scientists said. It also adds to the evidence that comets could have been a source of the complex organic molecules necessary for the emergence of life.

Research : Babies born during summer are more likely to be healthy adults

Women who were born in the summer are more likely to be healthy adults, suggests new research. Authors of a study published in the journal Heliyon, which involved almost half a million people in the U.K., say more sunlight-and therefore higher vitamin D exposure-in the second trimester of pregnancy might explain ...

Rosetta's 'rubber duck' comet was once two objects

Two comets crashed long ago to create the dumbbell-shaped Comet 67P/Churyumov-Gerasimenko, say scientists with a European Space Agency mission studying the comet. The reason for the odd form has been a mystery since the agency's spacecraft Rosetta, visiting the comet, revealed the shape in July 2014. Researchers attributed the shape either to ...

Ancient tsunami claimed to be 270 meters tall

A tsunami 73,000 years ago may have generated waves at least 270 meters (890 feet) tall, almost as high as New York's Chrysler Building, a study claim. However, the finding may not be the final word on a debate about ancient tsunamis, which other scientists have argued to be much smaller. The ...
