Astronomers narrow in on where Planet 9 might be hiding

Posted by in categories: mathematics, space

There are eight known planets in the Solar System (ever since Pluto was booted from the club), but for a while, there has been some evidence that there might be one more.

A hypothetical Planet 9 lurking on the outer edge of our Solar System. So far this world has eluded discovery, but a new study has pinned down where it should be. The evidence for Planet 9 comes from its gravitational pull on other bodies. If the planet exists, its gravity will affect the orbits of other planets.

So if something seems to be tugging on a planet, just do a bit of math to find the source. This is how Neptune was discovered when John Couch Adams and Urbain Le Verrier noticed independently that Uranus seemed to be tugged by an unseen planet.

Caltech’s Space-based Solar Power Project could provide Earth with limitless energy

Posted by in categories: solar power, space, sustainability

California Institute of Technology (Caltech) has received $100 million in funding for their Space-based Solar Power Project (SSPP), which is developing technology capable of generating solar power in space and beaming it back to Earth.

Caltech describes the project as “collecting solar power in space and transmitting the energy wirelessly to Earth through microwaves enables terrestrial power availability unaffected by weather or time of day. Solar power could be continuously available anywhere on Earth.”

The Space-based Solar Power Project has been underway since at least 2013 when the first donation arrived from Donald and Brigitte Bren. The gift is now being disclosed as SSPP nears a significant milestone: a test launch of multifunctional technology-demonstrator prototypes that collect sunlight and convert it to electrical energy, transfer energy wirelessly in free-space using radio frequency (RF) electrical power, and deploy ultralight structures that will be used to integrate them.

The first experimental realization of a dissipative time crystal

Posted by in categories: quantum physics, space

A time crystal is a unique and exotic phase of matter first predicted by the American physicist Frank Wilczek in 2012. Time crystals are temporal analogs of more conventional space crystals, as both are based on structures characterized by repeating patterns.

Instead of forming repetitive patterns across three-dimensional (3D) space, as space crystals do, time crystals are characterized by changes over time that occur in a set pattern. While some research teams have been able to realize these exotic phases of matter, so far, these realizations have only been achieved using closed systems. This raised the question of whether time crystals could also be realized in open systems, in the presence of dissipation and decoherence.

Researchers at the Institute of Laser Physics at the University of Hamburg have recently realized a time crystal in an open quantum system for the first time. Their paper, published in Physical Review Letters, could have important implications for the study of exotic phases of matter in quantum systems.

Dense ‘hot spots’ on a young star reveal what Earth’s sun may have looked in its infancy

Posted by in categories: materials, space

Astronomers may have captured the best view yet of matter colliding with the surface of a young star, findings that may shed light on what the sun looked like in its youth.

Newborn stars are surrounded by a disk of gas and dust from which planets, asteroids, comets and moons are born. The star’s magnetic field connects the star with this protoplanetary disk, “funneling material from the disk onto the star,” study lead author Catherine Espaillat, an astrophysicist at Boston University, told

Aerospace Corp. CEO sees winds of change in space procurement

Posted by in categories: business, security, space

The rapid commercialization of space and the establishment of the U.S. Space Force have created ideal conditions for change in the national security space business, says Steve Isakowitz, CEO of the Aerospace Corp. and former president of Virgin Galactic.

Aerospace, based in El Segundo, California, is a federally funded research and development center focused on analysis and assessment of space programs for the Defense Department, NASA and the National Reconnaissance Office.

In an interview with SpaceNews, Isakowitz says unprecedented opportunities are emerging for national security space organizations to capture commercial innovation. Defense programs won’t transform overnight, he says, but change is definitely in the air.

Newest Electra Meccanica Solo electric 3-wheeler packs a cargo trunk

Posted by in categories: business, food, security, space

There are a wealth of light fleet, business, and commercial applications where single occupants dominate,” says Paul Rivera, Electra Meccanica president and CEO. “From fast food franchise delivery and pizza delivery, to grocery delivery, small parcel and post, to tech repair and security firms, the Solo Cargo EV is the ideal solution to help companies minimize operational costs and maximize efficiency.

A hatchback is usually a solid choice for hauling cargo, but when the hatchback in question is a single-seat three-wheeler, things get a little more cramped. Canadian EV maker Electra Meccanica looks to solve this dilemma with a new cargo version of its three-wheeled all-electric Solo, replacing the usual lift-gate with a dedicated cargo trunk.

Adding a big rear box to a car as tiny and curvy as the Solo would usually be a drag on aesthetics, but Electra Meccanica has managed to integrate it pretty well. From the front 3/4 position, the new trunk looks almost like an aerodynamic Kamm tail element … or maybe a hyper-boost jet thruster.

Sail away: Rocket launch to test simple solution for space junk

Posted by in category: space

Engineers are set to test a device that could pull defunct spacecraft and used rocket parts back to Earth, allowing them to burn up harmlessly in the atmosphere.

Researchers at Purdue University in West Lafayette, Indiana, are launching a prototype drag sail Thursday aboard a rocket made by Firefly Aerospace, a private space company based in Austin, Texas. The mission is designed to assess how well the kitelike sail can de-orbit the rocket’s spent upper stage.

The launch is scheduled to take place at the Vandenberg Space Force Base in California between 6 p.m. and 10 p.m. PT.

Look: Unusual object called “The Accident” spotted

Posted by in category: space

It’s not quite a star and not quite a planet.

Astronomers spotted an unusual brown dwarf 50 light years from Earth. It may help unlock new discoveries about others in its class.
