Scientists Build a Teeny Tiny Tractor Beam
Tractor beams make intuitive sense. Matter and energy interact with each other in countless ways throughout the Universe. Magnetism and gravity are both natural forces that can draw objects together, so there’s sort of a precedent.
China launches 14 commercial satellites into orbit atop Long March 2D rocket (video)
A Long March 2D rocket lifted off from the Taiyuan Satellite Launch Center in northern China on Saturday (Jan. 14), sending 14 commercial satellites to orbit.
Instead of Building Structures on Mars, we Could Grow Them With the Help of Bacteria
NASA and the China National Space Agency (CNSA) plan to mount the first crewed missions to Mars in the next decade. These will commence with a crew launching in 2033, with follow-up missions launching every 26 months to coincide with Mars and Earth being at the closest point in their orbits. These missions will culminate with the creation of outposts that future astronauts will use, possibly leading to permanent habitats. In recent decades, NASA has conducted design studies and competitions (like the 3D-Printed Habitat Challenge) to investigate possible designs and construction methods.
Brilliant green comet loses part of its tail to solar storm in this stunning astrophotographer photo
An image taken by an Austrian comet hunter reveals a disconnection in Comet's C/2022 E3 (ZTF) tail that may have been caused by turbulent space weather.

Newfound alien planet has nuclear fusion going in its core
An international team of scientists has found a huge new alien world that's on the boundary between planet and "failed star."
Exploring the Outer Solar System Takes Power, Here’s a Way to Miniaturize Nuclear Batteries for Deep Space
As science and technology advance, we’re asking our space missions to deliver more and more results. NASA’s MSL Curiosity and Perseverance rovers illustrate this fact. Perseverance is an exceptionally exquisite assemblage of technologies. These cutting-edge rovers need a lot of power to fulfill their tasks, and that means bulky and expensive power sources.

Ancient 'guest star' may mark rare collision of stellar corpses
Centuries after Chinese and Japanese astronomers spotted a bright light in their skies, astronomers have pinned it to a stellar collision that unleashed a rare supernova 850 years ago.
Future-proofing ice measurements from space
With diminishing ice one of the biggest casualties of our warming world, it’s imperative that accurate measurements continue to be made for scientific research and climate policy, as well as for practical applications such as ship routing. To ensure that ESA and NASA are getting the best out of their ice-measuring satellites and to help prepare for Europe’s new CRISTAL satellite, the two space agencies along with the British Antarctic Survey and a team of scientists teamed up recently to carry out an ambitious campaign in Antarctica.
