NASA has released a collection of 50 stunning Hubble images to celebrate the veteran telescope’s 30th anniversary, which took place earlier this year. The images show 30 cosmic objects, ranging from planetary nebulae to galaxies in incredible detail, r… Continue reading Hubble gallery showcases 30 cosmic gems visible to amateur astronomers

New Gaia data reveals the motion of our galaxy in extravagant detail

ESA has made public a colossal data release from the agency’s Gaia observatory, which is currently engaged in a mission to survey 1 billion stars orbiting in the Milky Way. The data has already borne fruit, shedding light on the violent history of our … Continue reading New Gaia data reveals the motion of our galaxy in extravagant detail

Missing dark matter mystery reveals a galaxy entering death spiral

Astronomers are a step closer to solving a cosmic mystery, thanks to new Hubble data. Observations from the space telescope show a dwarf galaxy previously found to be missing most of its dark matter is being stripped of this matter by a larger nearby g… Continue reading Missing dark matter mystery reveals a galaxy entering death spiral

Earth is 2,000 light-years closer to galactic center than we thought

For two decades the Japanese VERA radio astronomy project has been gathering data to build up a 3D map of the position and velocity of objects revolving in our galaxy. The latest analysis indicates that the Earth is 2,000 light-years closer to the cent… Continue reading Earth is 2,000 light-years closer to galactic center than we thought

Starbirth in spite of feasting black hole prompts galaxy evolution rethink

Astronomers have found a distant galaxy that has managed to continue making new stars despite the presence of a disruptive “cold quasar” raging at its core. The discovery was made using the airborne SOFIA telescope, which, mounted in the side of a spec… Continue reading Starbirth in spite of feasting black hole prompts galaxy evolution rethink

Survey of Milky Way yields huge 50,000 x 25,000-pixel zoomable image

A team of astronomers has completed a massive survey of the Milky Way’s central bulge, which captured the light fingerprint of over 250 million stars, and could help provide new insights into our galaxy’s history and creation. A massive 50,000 x 25,000… Continue reading Survey of Milky Way yields huge 50,000 x 25,000-pixel zoomable image

Andrea Ghez Gazes into Our Galaxy’s Black Hole

Decades ago, Einstein predicted the existence of something he didn’t believe in — black holes. Ever since then, people have been trying to get a glimpse of these collapsed stars that represent the limits of our understanding of physics.

For the last 25 years, Andrea Ghez has had her sights …read more

Scientists calculate how much matter there is in the universe

Scientists have now estimated the total amount of matter in the universe, using a new, more precise method. By calculating the mass of hundreds of galaxy clusters, the team found that matter makes up less than a third of the contents of the universe.Co… Continue reading Scientists calculate how much matter there is in the universe

NASA “Sonification” project lets us hear the cosmos

We’re used to seeing the output of telescopes as images, but what if we could translate that data into sound? A new “Sonification” project from NASA’s Chandra X-ray Center has done just that, letting us hear the center of the Milky Way, the supernova r… Continue reading NASA “Sonification” project lets us hear the cosmos
