Dark matter has long been a mystery to astronomers, in no small part because it is so hard to measure directly. Its influence is plain when looking at its gravitational effects on objects such as far away galaxies, but measuring that influence directly has proved much trickier.
Gravity is a very predictable force – its strength diminishes with distance. While standing on the Earth, its influence is the strongest source of gravity. Similarly, if an object is floating around the solar system, the sun is likely its strongest source of gravity.
Astronomers Spot The Youngest Pair of Asteroids Ever Discovered in The Solar System
This makes them the youngest pair of asteroids ever discovered in the Solar System, by a factor of 10. The discovery could tell us more about how asteroids crumble, while raising some intriguing new questions.
"It's very exciting to find such a young asteroid pair that was formed only about 300 years ago, which was like this morning – not even yesterday – in astronomical timescales," says astronomer Petr Fatka of the Astronomical Institute of the Czech Academy of Sciences in Czechia.
7 ways the Webb Telescope will unlock the Solar System's secrets
If you know anything about the James Webb Space Telescope, it's probably that the telescope is designed to view very, very distant things .
NASA's new flagship science mission possesses instrument sensitivity reaching into the far-infrared, and an enormous, 21-foot diameter primary mirror — tools exceptionally well-tuned for imaging, say, the first galaxies to form in the universe billions of years ago, or characterizing the
Asteroid Ryugu Provides Record of Outer Solar System Material
In a recent study posted to the Research Square preprint* server as a submission to the journal Nature , researchers from Japan studied the unique and pristine record of materials from asteroid Ryugu.

NASA Selects Developer for Rocket to Retrieve First Samples From Mars
This illustration shows a concept for a set of future robots working together to ferry back samples from the surface of Mars collected by NASA's Mars Perseverance rover .
The award brings NASA a step closer to the first robotic round trip to bring samples safely to Earth through the Mars Sample Return Program.

The next 30 years of solar energy is likely to look very different than the past 30.
But in the coming decades, the evolution of solar energy technologies could be defined more by how they interact with other energy technologies, like wind and storage.

Extending the solar tariffs will undermine President Biden's climate goals - Niskanen Center
Last Friday, the Biden Administration announced that it would extend the Trump Administration's solar tariffs for four years but with modifications of a reduced scope. Extending the solar tariffs will do more harm than good to the U.S.
The Trump Administration placed tariffs on all imported solar cells and modules that started at 30 percent in February 2018 and declined to 15 percent in 2022. Countries that are deemed to be eligible for Generalized System of Preferences (GSP) were exempted from the tariffs.
Adding solar to California apartments could get easier… | Canary Media
" There are over 1 million homes with solar in California," Janis said in an interview. But " less than 1 percent of apartments or even single-family rental homes have solar energy."
That's largely because the interests of renters and property owners are not traditionally aligned when it comes to rooftop solar, a situation known as the split-incentive problem .
