Published Planetary system's second Earth-size world discovered


Using data from NASA's Transiting Exoplanet Survey Satellite, scientists have identified an Earth-size world, called TOI 700 e, orbiting within the habitable zone of its star -- the range of distances where liquid water could occur on a planet's surface. The world is 95% Earth's size and likely rocky.
Published Scientists find evidence for magnetic reconnection between Ganymede and Jupiter


In June 2021, NASA's Juno spacecraft flew close to Ganymede, Jupiter's largest moon, observing evidence of magnetic reconnection. A team has used Juno data to examine the electron and ion particles and magnetic fields as the magnetic field lines of Jupiter and Ganymede merged, snapped and reoriented, heating and accelerating the charged particles in the region.
Published Wide diversity of galaxies in the early universe


New data have revealed that the structures of galaxies in the early universe were much more diverse and mature than previously known. JWST's ability to see faint high redshift galaxies in sharper detail than Hubble allowed the team of researchers to resolve more features and see a wide mix of galaxies.
Published Astronomers find the most distant stars in our galaxy halfway to Andromeda


Astronomers have discovered more than 200 distant variable stars known as RR Lyrae stars in the Milky Way's stellar halo. The most distant of these stars is more than a million light years from Earth, almost half the distance to our neighboring galaxy, Andromeda, which is about 2.5 million light years away.
Published Scientists find pair of black holes dining together in nearby galaxy merger


While studying a nearby pair of merging galaxies scientists have discovered two supermassive black holes growing simultaneously near the center of the newly coalescing galaxy. These super-hungry giants are the closest together that scientists have ever observed in multiple wavelengths. What's more, the new research reveals that binary black holes and the galaxy mergers that create them may be surprisingly commonplace in the Universe.
Published NASA's retired Compton mission reveals superheavy neutron stars


Astronomers studying archival observations of powerful explosions called short gamma-ray bursts (GRBs) have detected light patterns indicating the brief existence of a superheavy neutron star shortly before it collapsed into a black hole. This fleeting, massive object likely formed from the collision of two neutron stars.
Published Galactic shock is shaping Stephan's Quintet in mysterious ways



Shockwaves resulting from the violent collision between an intruder galaxy and Stephan's Quintet are helping astronomers to understand how turbulence influences gas in the intergalactic medium. New observations have revealed that a sonic boom several times the size of the Milky Way has kick-started a recycling plant for warm and cold molecular hydrogen gas. What's more, scientists uncovered the break-up of a giant cloud into a fog of warm gas, the possible collision of two clouds forming a splash of warm gas around them, and the formation of a new galaxy.
Published Searching for the earliest galaxies in the universe


Astronomers have used data from NASA's James Webb Space Telescope (JWST) Early Release Observations and discovered 87 galaxies that could be the earliest known galaxies in the universe. The finding moves the astronomers one step closer to finding out when galaxies first appeared in the universe -- about 200-400 million years after the Big Bang.
Published NASA's Webb Telescope reveals links between galaxies near and far


A new analysis of distant galaxies imaged by NASA's James Webb Space Telescope shows that they are extremely young and share some remarkable similarities to 'green peas,' a rare class of small galaxies in our cosmic backyard.
Published Physicists confirm effective wave growth theory in space


Physicists have used spacecraft data to confirm an important theory of plasma physics that improves our understanding of space weather.
Published Space solar power technology demo launched into orbit


The launch represents the first in-situ test of the technology to harvest solar energy in space and transmit it to Earth.
Published Experimentalists: Sorry, no oxygen required to make these minerals on Mars


When NASA's Mars rovers found manganese oxides in rocks in the Gale and Endeavor craters on Mars in 2014, the discovery sparked some scientists to suggest that the red planet might have once had more oxygen in its atmosphere billions of years ago. But a new experimental study upends this view. Scientists discovered that under Mars-like conditions, manganese oxides can be readily formed without atmospheric oxygen.
Published Words prove their worth as teaching tools for robots


What is the best way to teach a robot? Sometimes it may simply be to speak to it clearly. Researchers found that human-language descriptions of tools can accelerate the learning of a simulated robotic arm lifting and using a variety of tools.
Published The physical intelligence of ant and robot collectives


Researchers took inspiration from ants to design a team of relatively simple robots that can work collectively to perform complex tasks using only a few basic parameters.
Published Should we tax robots?


A small tax on robots, as well as on trade generally, will help reduce income inequality in the U.S., according to economists.
Published Loon stratospheric balloons confirm wind data from Aeolus


ESA's novel Aeolus satellite reliably measures wind speed also in higher air layers and thus in a region of the atmosphere where other direct global wind measurements are relatively sparse. This is the result of a study for which data from the satellite were compared with wind observations from stratospheric balloons. Stratospheric balloons would provide highly accurate data on the horizontal wind speed and are therefore also suitable for the validation of future satellite missions.
Published New software based on Artificial Intelligence helps to interpret complex data


Experimental data is often not only highly dimensional, but also noisy and full of artefacts. This makes it difficult to interpret the data. Now a team has designed software that uses self-learning neural networks to compress the data in a smart way and reconstruct a low-noise version in the next step. This enables it to recognize correlations that would otherwise not be discernible. The software has now been successfully used in photon diagnostics at the FLASH free electron laser at DESY. But it is suitable for very different applications in science.
Published New winged robot can land like a bird


Researchers have developed a method that allows a flapping-wing robot to land autonomously on a horizontal perch using a claw-like mechanism. The innovation could significantly expand the scope of robot-assisted tasks.
Published Designing better battery electrolytes


Scientists give the lay of the land in the quest for electrolytes that could enable revolutionary battery chemistries.
Published Ancient asteroid grains provide insight into the evolution of our solar system


The UK's national synchrotron facility, Diamond Light Source, was used by a large, international collaboration to study grains collected from a near-Earth asteroid to further our understanding of the evolution of our solar system. Researchers brought a fragment of the Ryugu asteroid to Diamond's Nanoprobe beamline I14 where a special technique called X-ray Absorption Near Edge Spectroscopy (XANES) was used to map out the chemical states of the elements within the asteroid material, to examine its composition in fine detail.
