In search for a planet better than Earth: 24 top contenders from more than 4000 exoplanets.
Do we need to change our search parameters when looking for extraterrestrial life?
Paris, 4 October 2020. – A New York court has confirmed OneWeb’s rescue plan and put it back on track to launch its services in 2021, the London-based LEO operator announced.
The U.S. Bankruptcy Court for the Southern District of New York confirmed OneWeb’s Chapter 11 reorganization plan, ensuring that the company remains on target to resume business operations and deploy the initial 650 LEO satellite constellation under its new ownership, OneWeb said.
“The transactions outlined in the Plan will be implemented following receipt of customary regulatory approvals, which are expected by the end of 2020. In the meantime, OneWeb is resuming operations and readying its commercial services which are planned to start next year.”
Cygnus 14 Capture

With increasingly sophisticated Russian submarines prowling the Atlantic, the U.S. Navy is working harder to keep track of what’s happening off the U.S. coast.
The Navy’s focus on anti-submarine warfare waned during the Middle East wars, but attention is shifting, underscored by Exercise Black Widow 2020 in the North Atlantic between September 12 and 18.
The deterioration of Russia’s navy in the decade after the Cold War “allowed a lot of folks to think that the homeland is a sanctuary from Russian forces,” Vice Adm. Daryl L. Caudle, commander of Naval Submarine Forces, told reporters on September 16.
“But it’s pretty well known now that our homeland is no longer a sanctuary, so we have to be prepared here to conduct high-end combat operations in local waters,” Caudle added.
Mars, our second closest cosmic cousin, has been in our collective imagination for decades. Between fantasies of martian visits and the promise of water under its icy surface, Mars doesn’t need to do much to be in our collective good books.
But very soon, Mars is not just going to be close to our hearts, but also nearest to our actual planet — a mere 62.1 million kilometres (38.6 million miles) away from Earth.
This is the closest it’ll be for the next 15 years. And it means that stargazing is highly recommended as Mars will be bright, big and easy to see with or without a telescope.
Even the most optimistic estimates of neutron star collision frequency can’t account for the sheer abundance of gold and other elements in the Universe. This was a surprise. It looks like spinning supernovae with strong magnetic fields could be the real source of the majority of these elements.” ates of neutron star collision frequency can’t account for the sheer abundance of gold and other elements in the Universe.

One of the greatest mysteries in our Universe is right here on our own doorstep. No, closer — it’s in every fibre of our being.
At least 3.7 billion years ago, a few simple molecules worked together to create something new. Then a few more. And, somehow, these snowballing combinations eventually produced the first very basic living organisms that would evolve and branch out to become all life on Earth.
We don’t know the order it happened in; heck, we don’t even know when or where it happened. But new research is showing us the possibilities.
A rock structure, built deep underground, is one of the earliest hominin constructions ever found.
An international team of Johannes Kepler University researchers is developing robots made from soft materials. A new article in the journal Communications Materials demonstrates how these kinds of soft machines react using weak magnetic fields to move very quickly—even grabbing a quick-moving fly that has landed on it.
When we imagine a moving machine, such as a robot, we picture something largely made out of hard materials, says Martin Kaltenbrunner. He and his team of researchers at the JKU’s Department of Soft Matter Physics and the LIT Soft Materials Lab have been working to build a soft materials-based system. When creating these kinds of systems, there is a basic underlying idea to create conducive conditions that support close robot-human interaction in the future—without the solid machine physically harming humans.
Over the coming months, operations will begin at three existing underground detectors — in the United States, Italy and China — that search for dark-matter particles by looking for interactions in supercooled vats of xenon. Using a method honed over more than a decade, these detectors will watch for telltale flashes of light when the nuclei recoil from their interaction with dark-matter particles.
Researchers have spent decades searching for the elusive particles — a final generation of detectors should leave them no place to hide.
