Chinese scientists have made a groundbreaking milestone in nuclear fusion. They have announced a major achievement in discovering an advanced magnetic field structure “for the first time in the world” using the Huanliu-3 (HL-3) tokamak, also known as China’s “artificial sun.”
The discovery is the result of the first round of international joint experiments conducted on the HL-3 tokamak, a project that opened to global collaboration at the end of 2023.
Most distant spacecraft, #Voyager1, is now returning data from all four science instruments for the first time following a technical issue last November.
NASA’s Voyager 1 spacecraft is conducting normal science operations for the first time following a technical issue that arose in November 2023.
The team partially resolved the issue in April when they prompted the spacecraft to begin returning engineering data, which includes information about the health and status of the spacecraft. On May 19, the mission team executed the second step of that repair process and beamed a command to the spacecraft to begin returning science data. Two of the four science instruments returned to their normal operating modes immediately. Two other instruments required some additional work, but now, all four are returning usable science data.
The four instruments study plasma waves, magnetic fields, and particles. Voyager 1 and Voyager 2 are the only spacecraft to directly sample interstellar space, which is the region outside the heliosphere — the protective bubble of magnetic fields and solar wind created by the Sun.
The orbiting laboratory has a unique view of Earth and its surroundings.

A future space observatory could use exo-eclipses to tease out exomoon populations.
If you’re like us, you’re still coming down from the celestial euphoria that was last month’s total solar eclipse. The spectacle of the moon blocking out the sun has also provided astronomers with unique scientific opportunities in the past, from the discovery of helium to proof for general relativity. Now, eclipses in remote exoplanetary systems could aid in the hunt for elusive exomoons.
A recent study out of the University of Michigan in partnership with Johns Hopkins APL and the Department of Physics and the Kavli Institute for Astrophysics and Space Research at the Massachusetts Institute of Technology entitled “Exomoons & Exorings with the Habitable Worlds Observatory I: On the Detection of Earth-Moon Analog Shadows & Eclipses,” posted to the arXiv preprint server, looks to use a future mission to hunt for eclipses, transits and occultations in distant systems.

The three companies will compete for orders over the contract period starting in fiscal year 2025 through 2029. Under the NSSL program, the Space Force orders individual launch missions up to two years in advance. At least 30 NSSL Lane 1 missions are expected to be competed over the five years.
LAFAYETTE, Colo. - The U.S. National Aeronautics and Space Administration (NASA) has selected RTX’s small satellite manufacturer and mission services provider Blue Canyon Technologies in Lafayette, Colo., to build two 12U CubeSat buses for NASA’s PolSIR mission.
The PolSIR mission will study ice clouds that form at high altitudes throughout tropical and sub-tropical regions. In addition to designing and manufacturing the bus platforms, Blue Canyon will also provide mission operations services.
The PolSIR instrument –Polarized Submillimeter Ice-cloud Radiometer– will observe the full diurnal cycle of high-altitude ice clouds to improve climate forecasts and provide climate models with important insights into how Earth’s atmosphere will change in the future.
Read about NASA’s latest demonstration for its laser communication system!
NASA astronauts Randy Bresnik, Christina Koch, and Kjell Lindgren, and other NASA employees recently sent images and videos of their pets to the International Space Station (ISS) via the agency’s Space Communications and Navigation (SCaN) program to further test laser communications between ground-based stations and space-based systems, including the ISS. This demonstration holds the potential to further enhance laser communications systems that could be useful for long-term space missions.
For this demonstration, the SCaN program used its elaborate and coordinated system consisting of the High-Rate Delay Tolerant Networking (HDTN), which is run by NASA’s Glenn Research Center and capable of sending data at quadruple the speeds of current DTN technology; NASA’s Laser Communications Relay Demonstration (LCRD), which orbits at 22,000 miles above the Earth; and the Integrated LCRD Low Earth Orbit User Modem and Amplifier Terminal (ILLUMA-T) payload attached to the ISS.
An international team of astronomers has used NASA’s James Webb Space Telescope to study the disk of gas and dust around a young, very low-mass star. The results reveal the largest number of carbon-containing molecules seen to date in such a disk. These findings have implications for the potential composition of any planets that might form around this star.
Machine learning revolutionizes distance measurement in astronomy, providing precise estimates for gamma-ray bursts and aiding in cosmic exploration.
The advent of artificial intelligence (AI) has been hailed by many as a societal game-changer, as it opens a universe of possibilities to improve nearly every aspect of our lives.
Astronomers are now using AI, quite literally, to measure the expansion of our universe.
