A newly discovered crescent of galaxies spanning 3.3 billion light-years is one of the world’s largest known structures, challenging some of astronomers’ most fundamental assumptions about the universe.

The epic arrangement known as the Giant Arc is made up of galaxies, galaxy clusters, and a lot of gas and dust. It is located 9.2 billion light-years away and stretches across roughly a 15th of the observable universe.

Its discovery was “serendipitous,” according to Alexia Lopez, a doctoral candidate in cosmology at the University of Central Lancashire (UCLan) in the United Kingdom. Lopez was creating maps of things in the night sky using light from approximately 120,000 quasars, which are distant brilliant cores of galaxies where supermassive black holes consume material and produce energy.

Scientists on Wednesday said that they have successfully stirred a strange matter called a “supersolid” – which is both rigid and fluid – for the first time, providing direct proof of the dual nature of this quantum oddity.

In everyday life, there are four states of matter – solid, liquid, gas, and the rarer plasma.

But physicists have long been investigating what are known as “exotic” states of matter, which are created at incredibly high energy levels or temperatures so cold they approach absolute zero (−273.15 degrees Celsius or-459.67 degrees Fahrenheit).

Using data from NASA’s JWST and Chandra X-ray Observatory, a team of U.S. National Science Foundation NOIRLab astronomers have discovered a supermassive black hole at the center of a galaxy just 1.5 billion years after the Big Bang that is consuming matter at a phenomenal rate — over 40 times the theoretical limit. While short lived, this black hole’s ‘feast’ could help astronomers explain how supermassive black holes grew so quickly in the early Universe.

Supermassive black holes exist at the center of most galaxies, and modern telescopes continue to observe them at surprisingly early times in the Universe’s evolution. It’s difficult to understand how these black holes were able to grow so big so rapidly. But with the discovery of a low-mass supermassive black hole feasting on material at an extreme rate, seen just 1.5 billion years after the Big Bang, astronomers now have valuable new insights into the mechanisms of rapidly growing black holes in the early Universe.

LID-568 was discovered by a cross-institutional team of astronomers led by International Gemini Observatory/NSF NOIRLab astronomer Hyewon Suh. They used the James Webb Space Telescope (JWST) to observe a sample of galaxies from the Chandra X-ray Observatory’s COSMOS legacy survey. This population of galaxies is very bright in the X-ray part of the spectrum, but are invisible in the optical and near-infrared. JWST’s unique infrared sensitivity allows it to detect these faint counterpart emissions.

The world’s first wooden satellite, built by Japanese researchers, was launched into space on Tuesday, in an early test of using timber in lunar and Mars exploration.

LignoSat, developed by Kyoto University and homebuilder Sumitomo Forestry, will be flown to the International Space Station on a SpaceX mission, and later released into orbit about 400 kilometers (250 miles) above the Earth.

Named after the Latin word for “wood,” the palm-sized LignoSat is tasked to demonstrate the cosmic potential of the renewable material as humans explore living in space.

Nokia’s investigation of recent claims of a data breach found that the source code leaked on a hacker forum belongs to a third party and company and customer data has not been impacted.

The statement comes in response to threat actor IntelBroker earlier this week releasing data belonging to Nokia, allegedly stolen after breaching a third-party vendor’s server.

The hacker tried to sell the data, claiming that it includes SSH keys, source code, RSA keys, BitBucket logins, SMTP accounts, webhooks, and hardcoded credentials, but they decided to leak it after Nokia denied the breach.
