Scientists discover bands of clouds streaking across a brown dwarf

Astronomers have detected something interesting on the surface of a cool star-like body known as a brown dwarf. The team of astronomers has identified what appear to be bands of clouds that are streaking across the surface of the brown dwarf. Those cloud bands are said to resemble clouds that stripe the surface of Jupiter and were discovered using a technique called polarimetry.

Researchers have created a working rotating detonation engine

Researchers have created a working rotating detonation engine

A team of researchers in Florida, working with the United States Air Force, claim to have built and tested an experimental model of a rotating detonation rocket engine. This type of engine uses spinning explosions inside a ring channel to create extremely efficient thrust. The engine is capable of running until the fuel is turned off.

Tom Cruise, SpaceX to shoot a film on the International Space Station

Tom Cruise, SpaceX to shoot a film on the International Space Station

There have been countless movies that have been set in outer space but not all of them can make a claim to be really based on reality. For that to happen, one will have to actually be in space or at least shoot some scenes there. Considering the logistics, not to mention legal and regulatory requirements, of that stunt, it's no surprise that almost no one has even bothered to do so. Tom Cruise and SpaceX, however, want to change that and they have their eyes on the ISS from the get-go.

MIT researchers think life may thrive on hydrogen planets

MIT researchers think life may thrive on hydrogen planets

Sara Seager, the Class of 1941 Professor of Planetary Science, Physics, and Aeronautics and Astronautics at MIT, wants to avoid a situation where humans might encounter alien organisms but fail to recognize it as actual life. Seager wants to cast a wider net when looking for environments beyond our own that might be habitable. Seager and fellow researchers recently published a paper noting observations and laboratory studies that show microbes can survive and thrive in atmospheres that are dominated by hydrogen.

Stanford researchers demonstrate a new method to transmit electricity wirelessly

Engineers at Stanford have demonstrated a new method of transmitting electricity wirelessly to multiple devices. The wireless electricity transmission system they developed could send electricity to electric cars, robots, and drones as they move. The team says that the technology would need to be scaled up to be able to power electric cars as they drive on highways or to power robots on factory floors.

Researcher’s ultrafast camera snaps 70 trillion frames per second

Researcher’s ultrafast camera snaps 70 trillion frames per second

A researcher from Caltech named Lihong Wang has created a new ultrafast camera capable of taking images extremely quickly. The ultrafast camera can snap images at a rate of 70 trillion per second. The team says in the length of time it takes a person to blink their eye; the camera can take trillions of pictures.

These “superhuman eyes” will give NASA’s Perseverance rover its edge on Mars

NASA has detailed the advanced cameras that will give the Perseverance rover its "eyes" on Mars, a huge step up from previous Martian robots, as it readies the lab-on-wheels for its big trip to the red planet. If all goes to plan, NASA intends to launch Perseverance sometime in late July or early August of this year.

New 3D metal printer uses LED light source

New 3D metal printer uses LED light source

Researchers at Graz University of Technology have created a new type of 3D printer that uses LED instead of laser sources for additive manufacturing of metal parts. The new 3D printer can optimize 3D metal printing for construction time, metal powder consumption, device costs, and post-processing work. The team behind the 3D printer has applied for a patent on the technology.

Tiny spinobots use rat spinal cords to walk

Tiny spinobots use rat spinal cords to walk

Researchers at the University of Illinois at Urbana-Champaign have created tiny biological robots that can make walking motions thanks to rat spinal cord segments. The tiny robots that the researchers developed called spinobots and are powered by rat muscle and spinal cord tissue on a soft 3D printing hydrogel skeleton. Past generations of the biological robots were able to move forward by simple muscle contraction.

Researchers find massive microplastic hotspots on the deep seafloor

Researchers find massive microplastic hotspots on the deep seafloor

Every year, plastic waste discarded by humans -- everything from plastic straws and food packaging to fishing nets and industrial products -- ends up in the oceans. This trash floats around, eventually bumping into each other, where it becomes trapped and forms an 'island' of trash. A new study sheds light on what happens to this plastic over time, namely the microplastic hotspots it can produce.

Virgin Galactic’s SpaceShipTwo glides in test flight over New Mexico

SpaceShipTwo has completed its first test flight conducted from Spaceport America in New Mexico, Virgin Galactic announced on Friday. The company called this a milestone flight, one that is paving the way for eventual commercial service. Virgin Galactic says the spaceplane achieved multiple test-points before ultimately landing safely back at Spaceport America.

NASA reprocessed Europa images from the ’90s to reveal stunning details

NASA reprocessed Europa images from the ’90s to reveal stunning details

NASA has reprocessed images of Jupiter's moon Europa that were captured by its Galileo spacecraft back in the 1990s. The reprocessed versions of the images reveal the moon's surface in stunning detail, highlighting what NASA refers to as 'chaos terrain' and a variety of details about the features found on the surface. The new versions of the images are made possible using modern image processing technologies.
