What would we look for in a distant exoplanet in the hunt for Earth-like worlds, and perhaps life? A recent observation carried out by the Hubble Space Telescope found tell-tale signatures from our home planet by looking at a familiar source under extraordinary circumstances: Earth’s Moon, during a total lunar eclipse.
Stars form from the collapse of dense clouds of gas and dust, which makes it very hard for astronomers to watch the process unfold. Recently the ALMA telescope has revealed a treasure trove of embryonic stars in the Taurus Molecular Cloud, illuminating how baby stars are born. The Atacama Millimeter/submillimeter Array (ALMA) in the Atacama … Continue reading “Seeing baby stars at every stage of their formation” The post Seeing baby stars at every stage of their formation appeared first on Universe Today .
Could lava tubes on the Moon and Mars play a role in establishing a human presence on those worlds? Possibly, according to a team of researchers.
Recent observations and theortetical work have brought us one step closer to resolving the mystery of what lies at the center of the supernova SN 1987A The post Astronomers Think They’ve Found the Neutron Star Remnant From Supernova 1987a appeared first on Universe Today .
The InSight lander is making progress on Mars. After many months of struggle and careful adaptation, the InSight lander’s ‘Mole’ is finally into the ground.
There’s a surprising phenomenon taking place in Mars’ atmosphere: during the spring and fall seasons on the Red Planet, large areas of the sky pulse in ultraviolet light, exactly three times every night. “The ultraviolet glow … is as bright in the ultraviolet as Earth’s northern lights,” said Zac Milby, of the University of … Continue reading “The Martian Sky Pulses in Ultraviolet Every Night” The post The Martian Sky Pulses in Ultraviolet Every Night appeared first on Universe Today .
A magnetar has been discovered throwing off bizarre blasts of radiation. Is this where fast radio bursts come from?
Magnetars are the ultimate aggressive star: intense magnetic fields, massive outbursts, the works. We’ve known that magnetars are capable of producing some of the most powerful blasts in the cosmos, but new observations reveal a different kind of radiation: radio waves. This could potentially solve the long-standing puzzle of the origins of the mysterious Fast … Continue reading “A magnetar has been discovered throwing off bizarre blasts of radiation
Astronomers have found an extrasolar planet around a main sequence star. Which isn’t a big deal. With a radio telescope
When neutron stars collide, they go out with a tremendous bang, fueling an explosion up to a thousand times more powerful than a supernova. But sometimes they go out with a whimper, and a recent suite of simulations is showing why: they turn into a black hole
An international team of astronomers discovered some surprising when studying a debris ring around our Milky Way: the remnants of an ancient globular cluster The post A Globular Cluster was Completely Dismantled and Turned Into a Ring Around the Milky Way appeared first on Universe Today .
Protoplanetary disks – where young stars are forming their families of planets – usually form concentric rings of gaps. But astronomers have recently spotted a surprising situation: an adolescent star surrounded by galaxy-like spiral arms.
We know that the carbon in your bones was formed long ago in the heart of a star. But how did that carbon actually make its way to your bones?
At first glance, it looks like something from an alien autopsy. A strange organ cut from a xenomorph’s thorax, under the flickering lights of an operating room in a top secret government facility, with venous tendrils dangling down to the floor, dripping viscous slime.
Is it possible that the aliens are not hiding, but sleeping and waiting for the Universe to get better? The post Beyond the Fermi Paradox V: What is the Aestivation Hypothesis? appeared first on Universe Today .
It’s August and that means the Perseid meteors are inbound, starting this weekend this shower is a sure-fire bet, though 2020 sees the spectacle go down under somewhat challenging circumstances. The post Meteors of August: Our Guide to the 2020 Perseids appeared first on Universe Today .
Twinkling stars might make for spectacular viewing on a hot summer’s night, but they are an absolute nightmare to astronomers. That twinkling is caused by disturbances in the Earth’s atmosphere, and can wreak havoc on brightness readings, a key tool for astronomers everywhere. Those readings are used for everything from understanding galaxy formation to the … Continue reading “Antarctica Is the Best Place On Earth for a Telescope, Is Also the Hardest Place to Put a Telescope” The post Antarctica Is the Best Place On Earth for a Telescope, Is Also the Hardest Place to Put a Telescope appeared first on Universe Today .
Astronomers have found another strange exoplanet in a distant solar system. This one’s an oddball because its size is intermediate between Earth and Neptune, yet it’s 50% more massive than Neptune
Orbiters are giving us a chance to study the surface of Mars closely, and some of the features that pop to prominence are dry river channels. There are over 10,000 of them
Since it launched in 2010, the Solar Dynamics Observatory has helped scientists understand how the Sun’s magnetic field is generated and structured, and what causes solar flares. One of the main goals of the mission was to be able to create forecasts for predicting activity on the Sun.
