An international team of astronomers has uncovered new evidence to explain how pulsing remnants of exploded stars interact with surrounding matter deep in the cosmos, using observations from NASA’s IXPE (Imaging X-ray Polarimetry Explorer) and other telescopes.

Scientists based in the U.S., Italy, and Spain, set their sights on a mysterious cosmic duo called PSR J1023+0038, or J1023 for short. The J1023 system is comprised of a rapidly rotating neutron star feeding off of its low-mass companion star, which has created an accretion disk around the neutron star. This neutron star is also a pulsar, emitting powerful twin beams of light from its opposing magnetic poles as it rotates, spinning like a lighthouse beacon.

The J1023 system is rare and valuable to study because the pulsar transitions clearly between its active state, in which it feeds off its companion star, and a more dormant state, when it emits detectable pulsations as radio waves. This makes it a “transitional millisecond pulsar.”

The ‘helicity barrier’ has been directly confirmed, offering new insights into the heating and formation of the solar wind. Scientists have long been puzzled by an unusual solar mystery: the Sun’s outer atmosphere, called the corona, is vastly hotter than the surface below it. Adding to the intrigu

Space Renaissance International (SRI) wants to celebrate the 50th Anniversary of the historical Apollo-Sojuz Rendezvous, occurred the 17 July 1975!

During the cold war age, American astronauts and Russian cosmonauts gave a beautiful example of friendship and collaboration. Space culture demonstrated to be very much higher than terrestrial warmongering attitude! And such a distinctive cultural tract was demonstrated even later, with the MIR space station and then the ISS. Up to our present days, when the need of an higher Peace Culture is more urgent than ever.

Bernard Foing (SRI President), Jerry Stone, Werner Grandl, Marie-Luise Heuser, and others, will celebrate and share their thoughts about this historical Anniversary.

SRI invites All to celebrate with us!

A detailed analysis of a stellar cluster has led to a possible explanation for several fast-moving runaway stars around the cluster.

The “altercation” happened 50,000 years ago: The binary star Mel 34 was ejected from a young star cluster at a speed of 100,000 mph (46 km/s)—the result of a violent interaction that seemed buried in the cosmic past. But a group of astronomy detectives has now reconstructed part of the cluster’s history and identified a five-star smashup as the most likely cause for Mel 34’s high-speed departure [1]. This unlikely collision offers important information about the fate of young, massive stars.

The star cluster R136 is a grouping of around 60,000 stars in the Large Magellanic Cloud, a small galaxy 160,000 light-years from Earth. The cluster is about 2 million years old, which is fairly young as clusters go. “R136 is very special because it’s the youngest and the most massive star cluster in the local group of galaxies,” says Simon Portegies Zwart from Leiden University in the Netherlands. Previous studies of R136 have identified several dozen “runaway” stars that have been kicked out of the cluster. Runaways are common around clusters, but their origins are not always clear. R136 is young, so it’s a good place to study the process that produces runaways, Portegies Zwart says.

NASA research has shown that cell-like compartments called vesicles could form naturally in the lakes of Saturn’s moon Titan.

Titan is the only world apart from Earth that is known to have liquid on its surface. However, Titan’s lakes and seas are not filled with water. Instead, they contain liquid hydrocarbons like ethane and methane.

On Earth, liquid water is thought to have been essential for the origin of life as we know it. Many astrobiologists have wondered whether Titan’s liquids could also provide an environment for the formation of the molecules required for life—either as we know it or perhaps as we don’t know it—to take hold there.
