The findings might help piece together the evolution of the universe.
Some 70,000 years ago, a rogue star duo whooshed by our solar system — and early humans probably saw it
If you happened to be alive 70,000 years ago, you’d be in for quite a show.
In the Pisces constellation, one star is busy devouring its own planetary offspring
Giving “family dinner” a whole new meaning.
Biomarker molecule discovered “in abundance” around alien star, but still no life
Turns out, planet farts are just like ours, but with chlorine!
The sun likely has a lost twin called ‘Nemesis’, as do most stars like it
It sounds like the plot of a bad movie — but it’s just science.
Researchers found a supermassive black hole choking on its meal
Greedy!
Black holes turn stars into spaghetti, devours them, then burp fire
If there’s one thing that black holes do extremely well, it’s drawing things to them and destroying them.
ESA’s Gaia observatory sends back first star chart showing a billion new stars
Seeing is believing.
First stars formed much later than we thought
The European Space Agency’s Planck satellite has revealed some information which may force us to rethink the evolution of the early Universe.
Star blast reveals water ‘snowline’ for first time ever
This space snow could help scientists better understand planet formation and evolution.
Origami battery that runs on a few drops of water could revolutionize biosensors
This disposable battery runs on bacteria and folds like an origami ninja star. Sold!
Lonely planet found in a family of stars
NASA astronauts have discovered a lonely planetary-like mass floating on its own, without a solar system. Imagine a galaxy, riddled with countless solar systems. Then zoom in slowly on a solar system – how do you picture it? There’s probably a star at the center, and several planets around it. That’s generally where we feel planets should be, rotating around
Hubble captures the death of a star, offering a glimpse of our sun’s final days
A spectacular image captured by the Hubble Space Telescope’s Wide Field Planetary Camera 2 (WFPC2) gives us a glimpse into how the Sun will look at its death.
3,200-year-old papyrus contains astrophysical information about the Algol star
Many ancient civilizations made astronomical notes, but according to researchers, this is the earliest historical document of naked eye observations on a variable star – Algol. Variable stars are stars with a varying brightness (as seen from Earth), and they probably held a special place in Egyptian astronomy – they made careful notes on these stars. Now, more than three
Newborn star fires lightsaber: as seen by Hubble
This celestial lightsaber does not lie in a galaxy far, far away, but rather inside our home galaxy.
Scientists find a tiny star with a huge storm — just like Jupiter’s
While the windy and overcast weather of a stormy day isn’t surprising on telluric planets, it’s not something most of us readily associate with stars. But it does happen — the best evidence for this is W1906+40, a distant dwarf star recently described in a study published in the Astrophysical Journal.
Newly discovered star’s chemistry puzzles researchers
A team of Argentinian astronomers, peering up in the night’s sky from the Astronomical Observatory of Córdoba has found a new, young lithium-rich giant star that they designated KIC 9821622. And they can’t explain where that lithium comes from.
Something is blocking light from a distant star, and one of the possibilities is an alien structure
It’s likely not aliens, but it could be – and it’s really, really strange.
How to weigh a star: a new mathematical method
A novel mathematical model can weigh the mass of a pulsar – a rapidly rotating magnetized neutran star – using principles of nuclear physics, rather than gravity. Up until now, the mass of a star could only be determined in relation with other bodies, based on the gravitational pull these exerted. Now, using the new model scientists will be able to study pulsars in isolation, allowing for more precise measurements than ever before.
Incredibly active galaxy cluster creates 800 stars every year
The gargantuan cluster is 9.8 billion light years away from us, houses at least 27 galaxies and has a combined mass equal to 400 trillion Suns.
