Unknown objects at the heart of the Milky Way are beaming radio signals, then mysteriously disappearing

The radio telescope at the Parkes Observatory at sunset near the town of Parkes, Australia, July 15, 2019.Stefica Nicol Bikes/Reuters Mysterious radio waves emanating from the center of the galaxy have astronomers stumped. Four objects have briefly emitted radio signals that don't resemble any known type of star. Scientists think each of the four signals could come from a new type of object unknown to astronomy.

Mysterious radio waves are radiating from an unknown object at the heart of the Milky Way, astronomers say

The radio telescope at the Parkes Observatory at sunset near the town of Parkes, Australia July 15, 2019. Stefica Nicol Bikes/Reuters Astronomers detected mysterious radio waves from the center of the galaxy that vary dramatically and seem to shut off at random. The waves' origin is unknown, so they hint at the existence of a new type of celestial object. The signal doesn't look like the kind that comes from stars, planets, or even dead stars. Mysterious radio waves are emanating f...

400,000 people are infected each year with coronaviruses carried by bats, an early study suggests. Researchers say the data could help prevent future pandemics.

A team of researchers set up a net to catch bats at the Khao Chong Pran Cave on September 12, 2020 in Ratchaburi, Thailand during a mission to understand the coronavirus's origins. Lauren DeCicca/Getty Coronaviruses from bats could infect 407,422 people each year, a study said. The findings could help target areas for surveillance and stop human virus outbreaks, they said. About 478 million people live in regions where the bats are, the researchers said. See more stories on Insider...

New research suggests 30 to 40 minutes of exercise is needed to 'offset' a day of sitting

Regular exercise can offset the negative health impacts of sitting all day. Nitat Termmee/Getty Images About 30 to 40 minutes of exercise could offset the increased risk of death from 10 hours of sitting. That's according to an analysis of nine studies involving more than 44,000 people wearing fitness trackers. Exercise can include physical activities like walking, cycling, playing with kids, or gardening. See more stories on Insider's business page. We know that spending hour afte...
