The supersharp radio "vision" of the National Science Foundation's Very Long Baseline Array (VLBA) has revealed previously unseen details in a jet of material ejected at three-quarters the speed of light from the core of a galaxy some 12.8 billion light-years from Earth. The galaxy, dubbed PSO J0309+27, is a blazar, with its jet pointed toward Earth, and is the brightest radio-emitting blazar ye

NASA has approved two heliophysics missions to explore the Sun and the system that drives space weather near Earth. Together, NASA's contribution to the Extreme Ultraviolet High-Throughput Spectroscopic Telescope Epsilon Mission, or EUVST, and the Electrojet Zeeman Imaging Explorer, or EZIE, will help us understand the Sun and Earth as an interconnected system. Understanding the physics th

This past week, the United States Space Force turned one year old. In the months leading up to the anniversary, the infant military branch started to form an image all its own. In July, the newly instituted Space Force unveiled its logo and new motto, Semper Supra, "Always Above." The motto was reminiscent of other military branches, like that of the Marine Corps "Semper Fidelis," meaning "Alway

Congress has added $1.3 billion into the Missile Defense Agency's fiscal 2021 budget, in excess of what the agency asked for in February. The agency had requested $9.13 billion, a $1.27 billion decrease from last year's budget, but also submitted a list of unfunded requirements that totaled nearly $1 billion. In the bill, lawmakers describe a "concerning" disconnect between the M

Other worlds aren't the only difficult terrain personnel will have to traverse in humanity's exploration of the solar system. There are some parts of our own planet that are inhospitable and hard to travel over. Inner Mongolia, a northern province of China, would certainly classify as one of those areas, especially in winter. But that's exactly the terrain team members from the China Aerospace Science and Technology Corporation (CASTC) had to traverse on December 16th to retrieve lunar samples from the Chang'e-5 mission. What was even more unique is that they did it with the help of exoskeletons.

Strangely enough, the workers wearing the exoskeletons weren't there to help with a difficult mountain ascent, or even pick up the payload of the lunar lander itself (which only weighed 2 kg). It was to set up a communications tent to connect the field team back to the main CASTC headquarters in Beijing.

The exoskeletons were designed to help people carry approximately twice as much as they would be able to. Local state media described a single person carrying 50kg over 100m of the rough terrain without becoming tired. Setting up communications equipment isn't all the exoskeletons are good for though. They were most recently used by Chinese military logistics and in the Himalayas, where the country has been facing down the Indian military over a disputed line of control.

Lengthened to the size of a tennis court, the five-layer sunshield of NASA's fully assembled James Webb Space Telescope successfully completed a final series of large-scale deployment and tensioning tests. This milestone puts the observatory one step closer to its launch in 2021. "This is one of Webb's biggest accomplishments in 2020," said Alphonso Stewart, Webb deployment systems lead fo

A combination of astrophysical measurements has allowed researchers to put new constraints on the radius of a typical neutron star and provide a novel calculation of the Hubble constant that indicates the rate at which the universe is expanding. "We studied signals that came from various sources, for example recently observed mergers of neutron stars," said Ingo Tews, a theorist in Nuclear
