By the end of 2022, China hopes to have its biggest space station yet orbiting around Earth, and the country’s space agency wants other nations to use it. China is inviting all members of the United Nations to submit applications to fly experiments on board the future habitat, dubbed the China Space Station. It’s a major step toward international cooperation for China and its space program, which has mostly relied on domestic hardware and capabilities in the past.

“The China Space Station belongs not only to China, but also to the world,” Shi Zhongjun, China’s ambassador to the UN, said in a statement about the initiative. As a guide for the decision, Zhongjun cited the 50-year-old Outer Space Treaty, which maintains that the exploration of space should be peaceful and benefit all countries.

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.

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

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.

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.
