Astrophysicists confirm cornerstone of Einstein’s Theory of Relativity

Posted by in category: space

An international collaboration of scientists has recorded the most accurate confirmation to date for one of the cornerstones of Einstein’s theory of general relativity, ‘the universality of free fall.”

The new research shows that the theory holds for strongly self-gravitating objects such as neutron stars. Using a radio telescope, scientists can very accurately observe the signal produced by pulsars, a type of neutron star and test the validity of Einstein’s theory of gravity for these extreme objects. In particular, the team analyzed the signals from a pulsar named “PSR J0337+1715’ recorded by the large radio telescope of Nançay, located in the heart of Sologne (France).

The universality of free fall principle states that two bodies dropped in a gravitational field undergo the very same acceleration independently of their composition. This was first demonstrated by Galileo who famously would have dropped objects of different masses from the top of Pisa’s tower to verify that they both reach the ground simultaneously.

Destiny 2: Beyond Light – Reveal Trailer

Posted by in categories: energy, space

Extreme graphics: 3.


A new power is born out of the ancient Pyramid ship above Europa’s frozen frontier, and a dark empire has risen beneath, united under the banner of the Fallen Kell of Darkness, Eramis. Join your fellow Guardians and bring down the empire at any cost – even if it means wielding the Darkness itself.
As the new threat emerges, so too does a mysterious new power – Stasis. Rooted in Darkness, Guardians will wield this new elemental power alongside Arc, Solar, and Void to dominate the battlefield. Titans, Warlocks, and Hunters each use Stasis in a different way, from slowing down foes with Stasis fields to encasing and shattering enemies with destructive might.

Robots with flexible feet walk 40% faster

Posted by in categories: robotics/AI, space

Researchers from the University of California San Diego (UCSD) have developed flexible feet that can help robots walk up to 40% faster on uneven terrain such as pebbles and wood chips. The work has applications for search-and-rescue missions, as well as space exploration.

“Robots need to be able to walk fast and efficiently on natural, uneven terrain, so they can go everywhere humans can, but maybe shouldn’t,” said Emily Lathrop, the study’s first author and a PhD student in the Jacobs School of Engineering at UCSD.

The researchers are presenting their breakthrough at the RoboSoft conference, taking place virtually from now until 15th July.

Hubble Looked as Far Back in Time as it Could, and Still Couldn’t See the First Generation of Stars in the Universe

Posted by in category: space

Astronomers don’t know exactly when the first stars formed in the Universe because they haven’t been observed yet. And now, new observations from the Hubble Space Telescope suggest the first stars and galaxies may have formed even earlier than previously estimated.

Why? We *still* haven’t seen them, even with the best telescope we’ve got, pushed to its limits.

A group of researchers used Hubble to look back in time (and space) as far as it could see, hoping to study these first generation of stars of the early Universe, which are called Population III stars. Hubble peered and squinted back to when the Universe was just 500 million years old – which is thought to be Hubble’s limit — and found no evidence of these very first stars.

Hubble Space Telescope snaps ultra-clear image of 13-billion-year-old globular cluster

Posted by in category: space

NASA/ESA’s Hubble Space Telescope has just captured a striking new image of a globular cluster some 44,000 light-years away from Earth and 13,000 light-years from the heart of the Milky Way. NGC 6441 is a 13-billion-year-old collection of galaxies existing in the southern constellation of Scorpius,…
