Missing ingredient for life finally found on a comet

Researchers have detected phosphorus on a comet – thereby completing the grocery list of elements that are essential for life. The discovery was made in data from comet 67P/Churyumov-Gerasimenko by the Rosetta probe a few years ago, strengthening the i… Continue reading Missing ingredient for life finally found on a comet

Eulogy To Arecibo: With Demise of a Unique Scientific Facility, Who Will Carry The Torch?

Few telescopes will get an emotional response from the general public when it is ultimately announced that they will be decommissioned. In the case of the Arecibo Observatory in Arecibo, Puerto Rico, the past months has seen not only astronomers but also countless people across the world wait with bated …read more

Second cable failure marks the end for famous Arecibo radio telescope

The Arecibo Observatory’s famous 1,000-ft (305-m) radio telescope is to be demolished after a second support cable failed. An assessment by the engineering firm of Thornton Tomasetti has determined that the radio dish and its 900-ton instrument platfor… Continue reading Second cable failure marks the end for famous Arecibo radio telescope

Earth’s nearest miss on record as small asteroid zips by closer than ISS

Last week, the Earth had its closest shave with an asteroid ever recorded, when a small space rock skimmed just 370 km (230 miles) above the surface. For comparison, that’s closer than the orbit of the International Space Station.Continue ReadingCatego… Continue reading Earth’s nearest miss on record as small asteroid zips by closer than ISS

Mean temperature of the universe is rising over billions of years

Earth isn’t the only place that’s heating up of late – the universe seems to be too. Astronomers at Ohio State University have taken the mean temperature of cosmic gas at different distances and ages, and found that it’s roughly 10 times hotter today t… Continue reading Mean temperature of the universe is rising over billions of years

Europa’s plumes may not originate from subsurface ocean

Jupiter’s moon Europa is a fascinating world, with a global subsurface ocean encased in an icy shell and plumes of water vapor that vent into space. A new study has simulated how these plumes might originate, revealing a surprisingly dynamic ice ball.C… Continue reading Europa’s plumes may not originate from subsurface ocean

Radio telescope detects a super-planet for the first time

Scientists in Europe and Hawaii have scored a world’s first by detecting a “super-planet,” also known as a cold brown dwarf or a failed star, using a radio telescope. Located 212 light-years away in the constellation of Hercules, the detection of BDR J… Continue reading Radio telescope detects a super-planet for the first time
