The question of life on Venus, of all places, is intriguing enough that a team of U.S. and Russian scientists working on a proposal for a new mission to the second planet — named Venera-D — are considering including the search for life in its mission goals.
It took NASA’s New Horizons space probe almost a decade to trek its way across the Solar System for 2015’s historic Pluto flyby – and when it got there, it discovered stunning towers of ice reaching 500 metres into the sky.
Pluto’s relationship with its moon Charon is one of the more unusual interactions in the solar system due to Charon’s size and proximity. It’s more than half of Pluto’s diameter and orbits only 12,000 or so miles away. To put that into perspective, picture our moon three times closer to Earth, and as large as Mars.
For decades, science popularizers have said humans are made of stardust, and now, a new survey of 150,000 stars shows just how true the old cliché is: Humans and their galaxy have about 97 percent of the same kind of atoms, and the elements of life appear to be more prevalent toward the galaxy’s center, the research found.
Orbiting debris could be making Tabby’s star blink
When you are a messy eater, it can take a long time to clean up after a meal. The slow dimming of Tabby’s star and the sudden dips in its light may be caused by an orbiting cloud of debris left over from when it partially gobbled a planet.
In 2022, a new, temporary star of sorts could be added to the night sky.
A group of astronomers has predicted that, five years from now, two faraway binary stars currently orbiting each other will collide, creating an explosion so bright that it will be visible to the naked eye. If accurate, the so-called “red nova” would be the first ever to be predicted by scientists on Earth.
A newly proposed technique could make it possible to search for life on alien planets much sooner than scientists had expected.

Monster black holes sometimes lurk behind gas and dust, hiding from the gaze of most telescopes. But they give themselves away when material they feed on emits high-energy X-rays that NASA’s NuSTAR (Nuclear Spectroscopic Telescope Array) mission can detect. That’s how NuSTAR recently identified two gas-enshrouded supermassive black holes, located at the centers of nearby galaxies.
Every few thousand years, an unlucky star wanders too close to the black hole at the center of the Milky Way. The black hole’s powerful gravity rips the star apart, sending a long streamer of gas whipping outward. That would seem to be the end of the story, but it’s not. New research shows that not only can the gas gather itself into planet-size objects, but those objects then are flung throughout the galaxy in a game of cosmic “spitball.”
Researchers have known for a while that a star called Gliese 710 is headed straight for our Solar System, but they have now worked out precisely when it should arrive.
Early Monday morning, while people on the East Coast were making coffee, dropping kids off at school, and cursing in traffic, a space rock as big as a 10-story building slipped past Earth.

The moon is made of moons, new simulations suggest. Instead of a single colossal collision forming Earth’s cosmic companion, researchers propose that a series of medium to large impacts created mini moons that eventually coalesced to form one giant moon.

The moon is a very old soul, it turns out.
A new analysis of lunar rocks brought to Earth by Apollo astronauts suggests that the moon formed 4.51 billion years ago — just 60 million years after the solar system itself took shape.
Some of the most distant stars in the Milky Way may have been lifted from another galaxy, research released Wednesday shows.
The unintended donor, known as the Sagittarius dwarf, is one of dozens of miniature galaxies that loop around the Milky Way. The Sagittarius dwarf is located about 3.4 million light-years away from Earth.
Rumor has it that the Chinese are testing that fabulous Sangraal of spacecraft propulsion—the EmDrive.
But the Chinese have been known to make some pretty fantastic, and insupportable claims; and there’s so far not a shred of evidence that the EmDrive actually works.
Scientists have looked to a distant red giant star, L2 Puppis, to forecast what the future of our Solar System will be.
What they’ve found is a star that’s almost a twin to what our Sun will become in about 6 billion years, and the discovery of an orbiting planet may be a preview of the Earth’s far-future fate.
A new study may explain how dust particles on the moon “levitate” just above the surface, even though there is no wind or flowing water on the moon to kick-up the material.
