How Paint And a Speaker Could Explain The Physics of The Sun’s Plasma Jets

by

The Sun is blanketed by spiking, ultra-hot jets of plasma created from electrically charged particles, and now scientists have figured out more about how these jets (or spicules) are created and driven up into the star’s atmosphere.   Via a series of laboratory experiments and models, a new study describes the spicules as being like … Read more

Gaze in Awe at This Breathtaking Hubble Image of an Outburst From a Baby Star

by

An epic outburst from a baby star still in the process of forming has been captured in a spectacular Hubble image. Roughly 1,250 light-years away, in the Orion molecular cloud star-forming region, jets from a protostar are punching through the cloud at supersonic speeds, heating the gas and causing it to glow brightly. The result … Read more

‘Heartbeat’ of Black Holes Solves Decades-Old Mystery of Plasma Jets

by

Fluctuating light from a black hole, observed over 15 years, has revealed more about the way these enigmatic objects feed. First, a structure called a corona forms around the outside of the event horizon. Then, powerful jets of plasma launch from the poles, punching material from the corona out into interstellar space at speeds close … Read more

Giant Bubbles Expanding From The Milky Way Could Be Explained by a Single Event

by

Two sets of giant bubbles that extend thousands of light-years above and below the plane of the Milky Way could have been produced by the same event, in spite of their significant difference in size.   They’re called the Fermi bubbles and the eROSITA bubbles, and astronomers believe they were the result of activity by … Read more

The Biggest Galaxy Ever Found Has Just Been Discovered, And It Will Break Your Brain

by

Astronomers have just found an absolute monster of a galaxy. Lurking some 3 billion light-years away, Alcyoneus is a giant radio galaxy reaching 5 megaparsecs into space. That’s 16.3 million light-years long, and constitutes the largest known structure of galactic origin.   The discovery highlights our poor understanding of these colossi, and what drives their … Read more

Astronomers See Black Hole Jets Blaze 16x Wider Than The Full Moon in Our Sky

by

Astronomers have captured a breathtaking radio wave image, showing our closest radio active black hole spewing out massive jets of plasma that span more than 16 times the size of the full moon in our sky.   The supermassive black hole in question is located in the center of the galaxy Centaurus A around 12 … Read more

Astronomers Spot a Ghostly ‘One-Winged Butterfly’ Blazing Through Space

by

The beautiful birth of a star has produced an exquisitely ethereal structure in interstellar space. It’s called the Chamaeleon Infrared Nebula, located about 520 light-years away, and in a new image from the NSF NOIRLab’s International Gemini Observatory in Chile, it appears in the sky like a pale gossamer butterfly wing.   At its core, … Read more
