New eclipsing double white dwarf binary discovered

Astronomers from the California Institute of Technology and elsewhere report the detection of a new eclipsing detached double white dwarf binary. The system, designated ZTF J2243+5242 has an orbital period of below 10 minutes, which makes it one of the shortest-period eclipsing binaries known to date. The finding is detailed in a paper published October 7 on arXiv.org.


Astronomers are interested in finding and studying double white dwarfs (DWDs), as their mergers are believed to produce new white dwarfs with higher masses. It is assumed that some high-mass white dwarfs in the solar neighborhood could be DWD merger products.

The Zwicky Transient Facility (ZTF), using the Palomar Observatory in California, is one of the most important astronomical surveys to search for double white dwarf binary systems. So

Those nations include Australia, Canada, Italy, Japan, Luxembourg, the United Arab Emirates, the United Kingdom and the United States of America.

NASA released the Artemis Accords in May to establish a framework of principles for safely and responsibly planning for humanity’s return to the moon.

“Artemis will be the broadest and most diverse international human space exploration program in history, and the Artemis Accords are the vehicle that will establish this singular global coalition,” said NASA Administrator Jim Bridenstine in a statement.

“With today’s signing, we are uniting with our partners to explore the Moon and are establishing vital principles that will create a safe, peaceful, and prosperous future in space for all of humanity to enjoy.”

It’s been more than a year since NASA and

Soyuz rocket departs for the international space station in historic final U.S.-Russian flight

BAIKONUR COSMODROME, Kazakhstan — Since the launch of Sputnik and Yury Gagarin from the desert steppe of Kazakhstan over 60 years ago, the history of spaceflight has been measured in milestones.

The first satellite, the first human in space, the first to the Moon. But the launch of Soyuz MS-17 on Wednesday was a different kind of milestone: the end of an era.

At 8.45 a.m. local time, a Soyuz rocket blasted off from Baikonur Cosmodrome, Russia’s sprawling and remote space launch facility in Kazakhstan, to the International Space Station.

It was the last time NASA paid for an American astronaut to fly with the Russian Space Agency, Roscosmos, on such a flight. Next year, for the first time since the start of the ISS program 20 years ago, Russia will fly all-Russian crews on Soyuz.

London, October 14, 2020 – Avenir LNG Limited (NOTC:AVENIR) today announced that its subsidiary Avenir (L) Pte. Ltd. has taken delivery of its first dual purpose liquefied natural gas bunkering and supply vessel (LBV) Avenir Advantage from Keppel Offshore & Marine, at the Nantong Shipyard, Jiangsu Province, China.

Following her maiden voyage, Avenir Advantage will commence a three-year charter to Petronas LNG Sdn Bhd in Malaysia; becoming the first dedicated LBV in South East Asia. She will supply LNG to fuel ships operating in the region and deliver LNG directly to Petronas small-scale customers.

Milorad Doljanin, CEO Avenir LNG Limited, commented: “With the delivery of the Avenir Advantage, we move one step closer to delivering our shareholders’ vision of creating a small-scale LNG supply and marketing portfolio.”

“The flexible design of our vessels allows us to support

Russian-US Crew Launches on Fast Track to the Space Station | World News

By VLADIMIR ISACHENKOV, Associated Press

MOSCOW (AP) — A trio of space travelers launched successfully to the International Space Station, for the first time using a fast-track maneuver to reach the orbiting outpost in just three hours.

NASA’s Kate Rubins along with Sergey Ryzhikov and Sergey Kud-Sverchkov of the Russian space agency Roscosmos lifted off as scheduled Wednesday morning from the Russia-leased Baikonur space launch facility in Kazakhstan for a six-month stint on the station.

For the first time, they tried a two-orbit approach and docked with the space station in just a little over three hours after lift-off. Previously it took twice as long for crews to reach the station.

They will join the station’s NASA commander, Chris Cassidy, and Roscosmos cosmonauts Anatoly Ivanishin and Ivan Vagner, who have been aboard the complex since April and are scheduled to return to Earth in a week.

Blue Origin launches, lands NASA moon landing sensor experiment

Oct. 13 (UPI) — Blue Origin successfully launched a NASA moon landing experiment aboard the company’s reusable New Shepard rocket Tuesday morning in Texas.

Liftoff took place from the company’s launch facilities about 150 miles east of El Paso.

The capsule separated from the rocket minutes into the flight and spent about 3 minutes at the height of an arc just over the Kármán line, the altitude at which space begins.

The rocket booster, with NASA sensors mounted on the exterior, landed smoothly about 7 minutes, 30 seconds after launch. The capsule landed with the aid of parachutes a few minutes later, kicking up a cloud of dust and sand.

The NASA experiment is part of the agency’s Tipping Point program, which seeks to demonstrate technology that can be adopted by private industry.

The project includes a collection of sensors designed to help locate a safe site on the moon

Machine learning model helps characterize compounds for drug discovery

Tandem mass spectrometry is a powerful analytical tool used to characterize complex mixtures in drug discovery and other fields.


Now, Purdue University innovators have created a new method of applying machine learning concepts to the tandem mass spectrometry process to improve the flow of information in the development of new drugs. Their work is published in Chemical Science.

“Mass spectrometry plays an integral role in drug discovery and development,” said Gaurav Chopra, an assistant professor of analytical and physical chemistry in Purdue’s College of Science. “The specific implementation of bootstrapped machine learning with a small amount of positive and negative training data presented here will pave the way for becoming mainstream in day-to-day activities of automating characterization of compounds by chemists.”

Chopra said there are two major problems in the field of machine learning used for chemical sciences. Methods used do not provide chemical understanding

Russia Launches Fresh Crew To ISS On Fast-track Journey

Two cosmonauts and a NASA astronaut blasted off on a high-speed journey to the International Space Station Wednesday, in the first such launch aboard a Russian capsule since SpaceX’s game-changing debut manned flight from US soil.

Sergey Ryzhikov and Sergey Kud-Sverchkov of Roscosmos and NASA’s Kathleen Rubins launched from the Russian-operated Baikonur cosmodrome in Kazakhstan at 0545 GMT on Wednesday.

A NASA TV commentator said everything was normal, citing communications between Russian mission control and the crew, while Roscosmos said the capsule had successfully gone into orbit.

Their journey will be the first manned flight to the ISS to last just over three hours before docking — a new fast-track profile that takes half the time of standard trips to the orbital lab.

One American, Two Russians Blast off to International Space Station | Top News

By Joey Roulette and Olzhas Auyezov

WASHINGTON/ALMATY (Reuters) – A Russian Soyuz spacecraft carrying a U.S. astronaut and two Russian cosmonauts blasted off from the Baikonur cosmodrome in Kazakhstan on Wednesday and successfully reached orbit, live footage broadcast by Russia’s space agency Roscosmos showed.

The crew members travelling to the International Space Station (ISS) are Kate Rubins, a NASA microbiologist who in 2016 became the first person to sequence DNA in space, and Russian cosmonauts Sergey Ryzhikov and Sergey Kud-Sverchkov.

The mission is the last scheduled Russian flight carrying a U.S. crew member.

Since the space shuttle program ended in 2011, NASA has relied on Russia to ferry its astronauts to the space station, an orbiting laboratory 250 miles above Earth that has housed international crews of astronauts continuously for nearly 20 years.

The U.S. space agency in 2014 contracted Elon Musk’s SpaceX and Boeing Co
