What factors impact how long it takes for a supermassive black hole binary to merge?

The post How Tilted Orbits Impact Supermassive Black Hole Collisions appeared first on Sky & Telescope.

Coincident with the rise of the dinosaurs, a large landmass filled most of the Arctic circle, potentially contributing to global cooling that advantaged the famous reptiles

A growing body of research suggests that GLP-1 drugs do more than control appetite and blood sugar. They could also fight inflammation

NASA's Transiting Exoplanet Survey Satellite has been searching for exoplanets since its launch in 2018, and it turns out it may have found plenty more of them than we had thought

What NASA’s Curiosity Rover found on Mars, how youth suicides dropped after the launch of the 988 crisis line, and what people think of AI voice clones

Smartwatches commonly use heart rate variability to monitor stress. Columnist Helen Thomson explores what this metric actually tells us, and whether it could also predict and diagnose depression – and help improve your mental health more generally

Physicists have long assumed that the universe is uniform at very large scales, but evidence is emerging this is wrong and suggests a way to resolve some of the biggest cosmological mysteries

The planet Uranus is a weird place. Not only does it roll around the Sun on its side once every 84.3 Earth years, it also sports a spindly set of rings corralled in some places by strange little moons. Two of those rings, the μ (mu) and ν (nu) rings are incredibly faint, which makes them challenging to study.

The best way to see comet R3 PanSTARRS’s long tail is with a camera.

Members of the National Science Board, which the U.S. Congress founded in 1950, were given no explanation for their termination

Einstein told us that massive objects bend light and he was of course, right. Across the universe, giant galaxies are acting as natural telescopes, warping and distorting the light of objects behind them into spectacular arcs and rings. Now the Euclid space telescope wants your help to find them and the scale of the hunt is unlike anything attempted before.

If humans are ever going to live permanently on Mars, someone is going to have to work out where all the raw materials, the food, they oxygen or the material for the structures to name just a few. A new study has tackled that unglamorous but absolutely critical question and the answer involves robots, asteroids, and one of the most complex supply chains ever designed.

NASA's planet hunting telescope has been busy. A new study has just sifted through the light of over 83 million stars and emerged with more than 11,000 potential worlds, including a confirmed giant planet orbiting a distant star. The results don't just add to our catalogue of planets. They fundamentally change where we look for them.

On April 17th, engineers at NASA's Jet Propulsion Laboratory (JPL) sent commands to shut down an instrument aboard Voyager 1 called the Low-energy Charged Particles experiment, or LECP. The nuclear-powered spacecraft is running low on power, and turning off the LECP is considered the best way to keep humanity's first interstellar explorer going.

ASTEP, the Antarctic Search for Transiting ExoPlanets, a small visible telescope operating at Concordia station, continues making a real impact in characterizing odd new exoplanetary systems.

Survey results suggest a rise in questioning of scientific evidence
