Researchers discover one of the most massive neutron stars

Using a pioneering method, researchers from the Astronomy and Astrophysics Group of the UPC and the Canary Islands Institute of Astrophysics (IAC) have found a neutron star of about 2.3 solar masses—one of the most massive ever detected. The study was published on the 23rd of May in the Astrophysical Journal and opens a new path of knowledge in many fields of astrophysics and nuclear physics.

Neutron stars (often called pulsars) are stellar remnants that have reached the end of their evolutionary life: they result from the death of a star of between 10 and 30 . Despite their small size (about 20 kilometres in diameter), have more mass than the sun, so they are extremely dense.

Researchers from the Universitat Politècnica de Catalunya (UPC) and the Canary Islands Institute of Astrophysics (IAC) used an innovative method to measure the mass of one of the heaviest stars known to date. Discovered in 2011 and called PSR J2215+5135, with about 2.3 solar masses it is one of the most massive of the more than 2,000 neutron stars known to date. Although a study published in 2011 reported evidence of a neutron star with 2.4 solar masses, the most massive neutron stars that had previously achieved a consensus among scientists, reported in 2010 and 2013, have 2 solar masses.

Thanos, Overpopulation, and How to Save the Universe

Now that some time has passed since the release of Avengers: Infinity War, we should probably talk about Thanos, the nigh-omnipotent “Mad Titan” at the heart of Marvel’s latest blockbuster, and how he perfectly embodies one of the most pervasive societal misconceptions circling the topic of life extension. This might, therefore, be the first post here on LEAF that necessitates a spoiler warning, so here it is!

SPOILER ALERT — IF YOU CARE ABOUT HAVING INFINITY WAR, WHICH IS AN EXCELLENT MOVIE THAT YOU SHOULD SEE, SPOILED, PLEASE ABANDON SHIP AND HEREUPON RETURN AFTER WATCHING

Jeff Bezos: ‘We will have to leave this planet … and it’s going to make this planet better’

LOS ANGELES – Deep thinkers have been saying for generations that we have to get off this rock and head for the stars, but the idea takes on a little more weight when the world’s richest person says it.

“We will have to leave this planet, and we’re going to leave it, and it’s going to make this planet better,” Jeff Bezos, the founder of Amazon retailing giant and the Blue Origin space venture, told me here on Friday night during a fireside chat at the National Space Society’s International Space Development Conference.

New MeerLICHT Telescope Can Track Deep Space — Here’s How It Works

Throughout history, astronomers have used both optical and radio telescopes to see and hear the universe. Now, a new project will combine both kinds of telescopes to combine the two senses so that scientists can get a more complete look at the universe in real-time.

MeerLICHT — which is Dutch for “more light” — is a new, fully robotic telescope that uses a 65-centimeter main mirror and a 100-megapixel camera that was unveiled Friday near Sutherland, South Africa, which is a few hours northeast of Cape Town. What makes this telescope different is that it will be connected to MeerKAT, a radio telescope that consists of 64 dishes and located 125 miles away. Both telescopes will scan the Southern Sky in matching fields of view. The project will be the first of its kind and size to listen as well as see into space.

In S.Africa, a unique telescope link-up scans deep space

Scientists in South Africa on Friday launched the world’s first optical telescope linked to a radio telescope, combining “eyes and ears” to try to unravel the secrets of the universe.

The device forms part of the Square Kilometre Array (SKA) project in the remote Karoo desert, which will be the world’s most powerful radio telescope system.

The latest move combines the new optical telescope MeerLITCH — Dutch for ‘more light’ — with the recently-completed 64-dish MeerKAT radio telescope, located 200 kilometres (125 miles) away.
