Webb telescope arrives safely. Now, Canadian astronomers are ready to unravel the mysteries of the universe

There's been a lot of breath-holding since the James Webb Space Telescope (JWST) launched on Dec. 25, but now astronomers can exhale: The $10-billion US telescope safely reached its destination Monday afternoon.

"We're just really excited to announce today that Webb is officially on station at its L2 orbit," Keith Parrish, Webb observatory commissioning manager at NASA's Goddard Space Flight Center said in a media teleconference. "This is just capping off a remarkable 30 days."

Lagrange Points are a kind of sweet spot in space where there is a pull between two objects like the sun and Earth and spacecraft can operate in either a stable or semi-stable orbit. Webb will sit at Lagrangian Point 2, or L2.

Webb is the successor to the Hubble Space Telescope, launched in 1990. Hubble is still hard at work, providing astronomers with insight into our universe, but Webb is a new and improved telescope that will peer further back to a time when our universe was in its infancy.

Although Webb has arrived safely at the Lagrange Point 2, the telescope will still undergo several months of testing to ensure everything is functioning properly.

After that, the science begins.

Nearly 1,000 mysterious strands revealed in Milky Way's center

Image

An unprecedented new telescope image of the Milky Way galaxy's turbulent center has revealed nearly 1,000 mysterious strands, inexplicably dangling in space.

Stretching up to 150 light years long, the one-dimensional strands (or filaments) are found in pairs and clusters, often stacked equally spaced, side by side like strings on a harp. Using observations at radio wavelengths, Northwestern University's Farhad Yusef-Zadeh discovered the highly organized, magnetic filaments in the early 1980s. The mystifying filaments, he found, comprise cosmic ray electrons gyrating the magnetic field at close to the speed of light. But their origin has remained an unsolved mystery ever since.

Now, the new image has exposed 10 times more filaments than previously discovered, enabling Yusef-Zadeh and his team to conduct statistical studies across a broad population of filaments for the first time. This information potentially could help them finally unravel the long-standing mystery.

The study is now available online and has been accepted for publication by The Astrophysical Journal Letters.

The Falcon 9 may now be the safest rocket ever launched

That's what you get for pissing off Elon. He wanted to buy rides to Mars. No one would sell to him, and laughed at him. So he re-invented their business and did it better, faster, cheaper, and safer.

First ever free-floating black hole found roaming through interstellar space

Image

An international team of researchers has confirmed that a possible microlensing event witnessed in 2011 was due to the presence of a free-floating black hole roaming through interstellar space—the first of its kind ever observed. The group has published a paper describing their findings on the arXiv preprint server.

Scientists have assumed for some time that there are many black holes wandering around in interstellar space, but until now they had not found one. This is due to the very nature of a black hole—they are difficult to spot against the black backdrop of space. Still, the evidence for their existence was strong. Prior research has shown that black holes are often formed when stars reach the end of their lives and their cores collapse, generally producing a supernova. And because many such supernova have been observed, it seemed clear that many black holes must have been created as a result.

But finding them has meant looking for lensing effects, when light from stars is bent by the pull of the black hole. Given the great distances, the lensing effect is slight, making it nearly impossible to detect using even the best modern telescopes. But luck prevailed in 2011 when two project teams looking for such lensing spotted a star that appeared to brighten for no apparent reason. Intrigued, the researchers with this new effort began analyzing the data from Hubble. For six years, they watched as the light changed, hoping that the change was due to magnification from a black hole. Then, they found something else—the position of the star appeared to change. The researchers suggest the change could only be due to an unseen moving object exerting a force that was pulling on the light as it passed by—an interstellar black hole. The researchers continued to study the star and its light, and eventually ruled out the possibility of any light coming from the lensing and also confirmed that the magnification had a long duration, both of which are prerequisites to confirming the existence of a black hole.
