Conditions for life may hinge on how fast the universe is expanding | Science | AAAS
Scientists have known for several years now that stars, galaxies, and almost everything in the universe is moving away from us
(and from everything else) at a faster and faster pace. Now, it turns out that the unknown forces behind the rate of this accelerating
expansion—a mathematical value called the cosmological constant—may play a previously unexplored role in creating the right conditions
for life.
That’s the conclusion of a group of physicists who studied the effects of massive cosmic explosions, called gamma ray bursts, on planets.
They found that when it comes to growing life, it’s better to be far away from your neighbors—and the cosmological constant helps thin
out the neighborhood.
“In dense environments, you have many explosions, and you’re too close to them,” says cosmologist and theoretical physicist Raul Jimenez
of the University of Barcelona in Spain and an author on the new study. “It’s best to be in the outskirts, or in regions that have not
been highly populated by small galaxies—and that’s exactly where the Milky Way is.”

Gaia > IoW_20160229
Alongside its main mission to chart the sky at unprecedented resolution, Gaia is moonlighting as a survey for transients
under the Gaia Photometric Science Alerts project. After reporting the discovery of hundreds of transients, Gaia Alerts
had a six-month pause in the second half of 2015. This break allowed for upgrades to the detection algorithms used to
find transients. In early 2016, the improved Gaia Alerts pipeline was turned on again. To date we have published in excess
of 140 transients at a rate of a little over 3 per day. Many of these transients are supernovae. All Gaia transients are
being published on the Photometric Science Alerts web page.
The first exciting supernova to be discovered by Gaia in 2016 was Gaia16aeg. This supernova was first discovered
independently by the ASAS-SN survey (as ASASSN-15lv) in mid 2015, and classified as a Type IIb supernova, at a relatively
close distance of around 60 million parsecs (Mpc). Type IIb supernovae arise from the core-collapse of a massive star
which has retained only a thin layer of its hydrogen envelope.
