Cosmic Ray Mystery Finally Cracked Thanks to Supermassive Black Hole Beaming Energy Straight at Earth

Every so often, protons and even entire atomic nuclei strike the Earth with extremely high energies—much higher than what scientists can produce in their most powerful physics experiments. Since the discovery of “cosmic rays” a hundred years ago, no one knew for sure where the most energetic of these particles came from—until now. Read More >>

Newly Discovered ‘Asteroid’ Is Far Freakier Than Astronomers Expected

When is an asteroid not an asteroid? When it’s a binary pair. Turns out that an asteroid discovered late last year is actually two gravitationally bound objects in orbit around each other. But this particular duo, dubbed 2017 YE5, belongs to an exceptionally rare class of near-Earth objects. Read More >>

New Analysis of Potentially Habitable Exoplanet Makes Us Hungry for Better Telescopes 

Eleven light-years from Earth, orbiting a dim red star, there’s an exoplanet called Ross 128b that, as we recently reported, has some the best prospects for life of any known distant world. New results may help astronomers figure out what the planet is made of—and they offer more evidence that it might be inside its parent star’s habitable zone. Read More >>

The Earth Is Farthest From the Sun Today, so Why Is It so Hot?

All-time heat records have been set around the world this week. As Britain bakes in its longest-ever heatwave in history, cities in continental Europe and Russia are sweltering too, as well as North American cities including Denver, Colorado; Burlington, Vermont; and Montreal, Quebec. But here’s something that might confuse you: Today is also aphelion day—the day in Earth’s orbit that it is farthest from the Sun. What gives? Read More >>

Did Something Massive Smash Into Uranus?

You might be aware of one of Uranus’ complexities: It spins on its side, and its moons orbit on that same rotated plane. New evidence strengthens the case that Uranus was smashed in a giant collision, resulting in its sideways orientation to its orbital plane and perhaps explaining some of the planet’s other mysteries.
