Earth’s low orbit is filling up, meaning radiation-tolerant cell designs are required as satellites head to higher orbits. Will these new ones do?

Scientists have developed a radiation-tolerant photovoltaic cell design that features an ultrathin layer of light-absorbing material. According to a new study published today (Nov .08) in the Journal of Applied Physics by AIP Publishing.

Significantly, the ultra-thin solar cells not only surpass earlier suggested thicker solar cells in resilience to irradiation; they also produce the same amount of power from converted sunlight after 20 years of use. Additionally, the novel photovoltaic cells could reduce load and considerably lower launch expenses. Barthel.

“This was completely unexpected.”

Stars are essentially large fiery balls of plasma, which is often referred to as the “fourth state of matter” as it forms when gas is heated into a soup of positively charged ions and negatively charged electrons.

The star’s magnetic field is so strong it appears to have “frozen” its surface into a solid outer crust, a press statement reveals.

With cost overruns and milestones not met, it is a wonder that NASA and Boeing aren’t headed for a divorce.

Agency budgetary report shows tens of billions spent on Boeing contracts that have yet to deliver. Much cheaper alternatives exist.

It may be known as a rocky, red planet but evidence is mounting that salty water exists at the base of polar deposits on Mars.

University of Southern Queensland’s Professor Graziella Caprarelli is part of an international team investigating bright reflection signals below the Martian surface, first spotted in data acquired between 2010 and 2019 by the radar sounder MARSIS on board Mars Express.

The primarily Italian team proposed that the reflections pointed to a patchwork of salty lakes, publishing their research in Science in 2018 and in Nature Astronomy in 2021. Recently a new collaboration between the Italian team and U.S.-based researchers provided new evidence further corroborating this interpretation.

NASA combined 18 all-sky images to create a timelapse of the night sky.

The Universe is over 13 billion years old, so a 12-year slice of that time might seem uneventful. But a timelapse movie from NASA shows how much can change in just over a decade.

A new study from the University of Central Florida has found strong support that the outgassing of molecules from comets could be the result of the composition from the beginning of our solar system.

The results were published today in The Planetary Science Journal.

The study was led by Olga Harrington Pinto, a doctoral candidate in UCF’s Department of Physics, part of the College of Sciences.

One of the oldest stars in the Milky Way has been located by astronomers from the University of Warwick.

The oldest rocky and icy planetary system identified is from the oldest white dwarf star in our galaxy and is accreting debris from circling planetesimals, according to a new study published in Monthly Notices of the Royal Astronomical Society on Saturday.

If you wake up early Sunday morning and see a small, bright object streaking through the sky, it could be a rocket that is being launched from the NASA Wallops Flight Facility in eastern Virginia.

NASA officials say the rocket may be visible from Delaware, Maryland, New Jersey, North Carolina, Pennsylvania, Virginia and West Virginia, along with Connecticut and lower New York state, shortly after liftoff — scheduled for 5:50 a.m. Sunday, Nov. 6.

The Northrop Grumman Antares rocket will be delivering supplies and science experiments to the International Space Station, NASA said. It will be the agency’s 18th resupply mission for the space station.

Until now, Mars.

Mars is the second smallest planet in our solar system and the fourth planet from the sun. It is a dusty, cold, desert world with a very thin atmosphere. Iron oxide is prevalent in Mars’ surface resulting in its reddish color and its nickname “The Red Planet.” Mars’ name comes from the Roman god of war.
