NASA Planet-Hunting Telescope Spots Massive Burp from a Comet | Space

Scientists have caught their best-ever look at a comet belching out ice, dust and gas — and the observations came courtesy of a mission designed to hunt for alien worlds.

Comet outbursts are natural but difficult to spot, since scientists don't quite understand their cause. What's clear is the result: A massive blast of material that makes the comet temporarily appear much brighter. New research used lucky observations gathered by NASA's Transiting Exoplanet Survey Satellite (TESS) of such an outburst on Comet 46P/Wirtanen before it swung past Earth a year ago.

Scientists Found a Planet Orbiting a Dead Star, a Glimpse Into Our Future - VICE

Based on the first discovery of a giant planet orbiting a white dwarf, reported in two new papers in the journals Nature and Astrophysical Journal Letters , researchers now believe that this hypothetical alien would be able to observe signatures of our Solar System's largest planets—Jupiter, Saturn, Uranus, and Neptune—just by looking at the dead Sun.

Though we've never seen them before, the new discovery suggests that there might be more of these giant planets circling dead stars. The researchers who found the first planet estimate that one in 10,000 white dwarfs have giant planets orbiting them at close range.

This may worth something:

Astronomers just found a dead star evaporating a giant, icy planet - CNET

An artist's impression of the WDJ0914+1914 system, where a dead white dwarf star is stripping away the atmosphere of a gas giant planet four times its size.

The puny sun exerts its dwindling force over the planet, stripping away its atmosphere and spinning an elegant disc of gas around itself in the process.

The oddball star carries the uninspired name WDJ0914+1914, located some 1,500 light years away, and the evaporating planet around it is thought to be something like Neptune based on the levels of hydrogen, oxygen and sulphur in the gassy disc. Yes, this planet is quite literally releasing silent but deadly stinky fumes across its solar system.

Love Beauty and Planet uses New York Times ad to call out beauty's sustainability problem

As beauty companies continue to negotiate the industry’s packaging problem, Unilever’s incubated brands Love Beauty and Planet and Love Home and Planet are taking a new approach for holiday.

“These are brands that were born out of purpose,” said Jain. “When we put the word ‘planet’ in the name of these brands, we took that responsibility very, very seriously.”

The New York Times has seen an uptick of beauty brands advertise in its print editions as of late, from Beautycounter to Glossier. Typically, these ads have been used to push bigger conversations within beauty such as its activism, in the case of Beautycounter, or diversity and inclusivity à la Glossier. And they don’t come cheap. The Times has a weekend audience of 4.6 million , and its media kit said ads of this kind range from $100,000 and $150,000.

Hidden Giant Planet Discovered Around Tiny White Dwarf Star [Video]

The giant planet is orbiting the white dwarf just outside the gas disc. The blast of high-energy photons that it receives from the white dwarfs evaporates its atmosphere, which is mainly composed of hydrogen, oxygen, and sulfur. Whereas much of the hydrogen is forced away from the white dwarf by its ultraviolet photons in a comet-like tail, oxygen and sulfur fall towards the white dwarf, forming the disc we have detected.

The first evidence of a giant planet orbiting a dead white dwarf star has been found in the form of a disc of gas formed from its evaporating atmosphere.
