The motion of a tiny number of charged particles may solve a longstanding mystery about thin gas disks rotating around young stars, according to a new study from Caltech.
These features, called accretion disks, last tens of millions of years and are an early phase of solar system evolution. They contain a small fraction of the mass of the star around which they swirl; imagine a Saturn-like ring as big as the solar system.
Could we eavesdrop on communications that pass through our solar system?
Massive objects like stars and black holes cause light to bend as it passes by due to the object's gravitational pull, according to Einstein's Theory of General Relativity.
"Astronomers have considered taking advantage of gravitational lensing as a way to essentially build a giant telescope to look at planets around other stars," said Jason Wright, professor of astronomy and astrophysics at Penn State who taught the course and is director of the Penn State ...
Porosity of the moon's crust reveals bombardment history | MIT News | Massachusetts Institute of ...
Around 4.4 billion years ago, the early solar system resembled a game of space rock dodgeball, as massive asteroids and comets, and, later, smaller rocks and galactic debris pummeled the moon and other infant terrestrial bodies. This period ended around 3.8 billion years ago.
Now MIT scientists have found that the porosity of the moon's crust, reaching well beneath the surface, can reveal a great deal about the moon's history of bombardment.
The Coolest Images Taken by NASA's New Horizons Spacecraft
NASA's New Horizons spacecraft has seen amazing things since it launched over sixteen years ago . It ha s cruised by Jupiter, peeked at erupting volcanos on Io, and most famously, zipped past Pluto, becoming the first spacecraft to visit a dwarf planet.
The spacecraft is now about 4.3 billion miles (6.9 billion km) from Earth, where it is operating normally and venturing deep into the Kuiper belt at speeds reaching 33,000 miles per hour (53,000 km/hr).

The next full moon will be Wednesday afternoon, July 13, 2022, appearing opposite the Sun in Earth-based longitude at 2:38 p.m. EDT. This will be on Thursday morning from the India Standard Time Zone eastward to the International Date Line.
Tesla (TSLA) achieves best solar deployment in years, but solar roof is still at a crawl - Electrek
Tesla has achieved its best solar deployment in the US residential solar market since back in 2017 after acquiring SolarCity, but its solar roof deployment is still at a crawl.
While Tesla fans and shareholders often like to say that Tesla is not just an “automaker” but a tech company, or even an AI-company based on CEO Elon Musk’s more recent comments, based on revenue, Tesla is very much an automaker.
China's future space missions could include a search for habitable exoplanets
The Chinese Academy of Sciences says that a search for habitable exoplanets could be one of several key Chinese space missions set to launch over the next several years.
A lot of different space agencies have big plans for how they want to explore the universe over the coming decade. For starters, NASA wants to put people on Mars in the 2030s. There’s even an ongoing mission to build a station orbiting the Moon .
NASA Helps Decipher How Some Distant Planets Have Clouds of Sand
Brown dwarfs – celestial objects that fall between stars and planets – are shown in this illustration with a range of temperatures, from hottest (left) to coldest (right). The two in the middle represent those in the right temperature range for clouds made of silicates to form.
Giant Comet Bernardinelli-Bernstein: What Comes Around Goes Around – Now.
An enormous comet is gliding through the outer reaches of the solar system, currently passing between the orbits of Uranus and Neptune.
We are accustomed to thinking of these distant worlds as orbiting in the outer reaches of the solar system.
And the sun is already warming it up, after millions of years of interstellar cold.
