Earlier observations using the European Southern Observatory's Very Large Telescope in Chile indicated the presence of an exoplanet in the Luhman 16AB system. *Another challenge to the Standard Model of particle physics Scientists are puzzled by the results of three particle physics experiments which are providing new hints of new physics beyond the Standard Model – the foundation of sciences understanding of the universe. The new studies are finding signs contradicting a key part of the Standard Model known as lepton universality. *India launches its new heavy lift rocket. India has launched its most powerful ever rocket the GSLV Mark 3 which will one day carry India’s first Manned spacecraft. The mission also marked the heaviest payload ever launched by

Until now astronomers were fairly sure our galaxy -- the Milky Way -- was located on one of the filaments. But now a new study claims we’re actually in a void. *Heavy rains on Mars A new study claims heavy rain on Mars reshaped the red planet’s surface carving out valley’s and river channels billions of years ago. The findings show changes in the Martian atmosphere made it rain harder and harder and form bigger drops. *X-37B space shuttle returns from record setting flight A United States Air Force X-37B space shuttle has returned to Earth following a record breaking two year long mission in orbit. The black and white winged spaceplane was launched way back on May 20th 2015. *The Square Kilo

The new research confirms that stars being consumed by a black hole really do fall through an event horizon into a singularity -- rather than crashing into some sort of hard object. *NASA’s new mission to touch the Sun The United States is to send a spacecraft into the Sun’s upper atmosphere – the corona. The Parker solar probe spacecraft will – quite literally touch the Sun – travelling to within 5.9 million kilometres of the Sun’s photosphere – its visible surface. *A possible Quark Nova Astronomers are looking at the possibility of a new and very different trigger for a strange type of supernova event called a quark nova. Core collapse or type II Supernova are usually generated by the explosive cataclysmic death of a star. If you're enjoying SpaceT
