China's Tianwen-2 mission blasted off on Wednesday, embarking on an epic 8-year journey that will help to unlock the secrets of an asteroid and a comet before delivering the precious cargo back to Earth. The spacecraft will first hunt down Kamoʻoalewa (asteroid 2016 HO3) which it will study for a year, extracting samples from its surface. After returning the sample to Earth, Tianwen-2 will head back out into the Solar System taking another 7 years to intercept the main belt comet 311P/Pan-STARRS. It will undertake a flyby study of this object that has never been studied before.

Lunar exploration is gaining momentum, but one of the biggest challenges remains the Moon’s long, cold night, which lasts about two weeks. To address this, a team of researchers has proposed deploying a constellation of solar power satellites in lunar orbit. These satellites would beam energy wirelessly to a base on the Moon, providing a continuous supply of 1,600 kW of power, day or night. Their proposal includes launching 300 satellites by 2035, supporting long term plans for establishing permanent lunar bases.

A team of geophysicists from the University of Chicago showed how clouds on exoplanets could enhance the search for biosignatures. Their findings could have significant implications for the Habitable Worlds Observatory (HWO) and other next-generation telescopes that will study exoplanets via direct imaging.

Engineers have developed a real-life Transformer that has the 'brains' to morph in midair, allowing the drone-like robot to smoothly roll away and begin its ground operations without pause. The increased agility and robustness of such robots could be particularly useful for commercial delivery systems and robotic explorers.

Studies of the Solar System's dynamics generally treat it in isolation and do not consider the influence a passing star could have on the orbits of the planets over time. According to a recent study by a team of astronomers, stars passing close to the Solar System could result in the loss of planets over the next 5 billion years.

A team identified herpes virus saimiri, which infects the T cells of squirrel monkeys, as a source of proteins that activate pathways in T cells that are needed to promote T cell survival.

In a major leap forward for genetic and biomedical research, scientists have developed a powerful new artificial intelligence tool that can predict the 3D shape of chromosomes inside individual cells -- helping researchers gain a new view of how our genes work.

A series of experiments support spectral data recently collected by the James Webb Space Telescope that found evidence that the icy surface of Jupiter's moon Europa is constantly changing. Europa's surface ice is crystallizing at different rates in different places, which could point to a complex mix of external processes and geologic activity affecting the surface.

Scientists have observed anyons -- quasiparticles that differ from the familiar fermions and bosons -- in a one-dimensional quantum system for the first time. The results may contribute to a better understanding of quantum matter and its potential applications.

A team of international astronomers have discovered a new cosmic object emitting both radio waves and x-rays.

A new study in Nature describes both the mechanism and the material conditions necessary for superfluorescence at high temperature.

Researchers have released new insights on a pilot program involving all-electric buses in Ithaca, NY, USA -- with implications for cities, schools and other groups that are considering the electrification of their fleets, as well as operators, policymakers and manufacturers.

Ultraviolet astronomical observations have always been hindered by one simple fact - the Earth's atmosphere blocks most UV photons, especially in the UV-C and UV-B range of 100-315nm wavelengths. So, astronomers must have a collector above the atmosphere if they want to know what is happening in those wavelengths. A consortium from Institut d'Estudis Espacials de Catalunya (IEEC) hopes to provide additional insight into that realm with their PhotSat mission, a CubeSat that will observe the whole sky in UV and visible light once every few days.

Generation starships may be the only way humans travel to other stars. These hypothetical spacecraft would travel at sub-light speed and take generations to reach their destination. Over the hundreds or even thousands of years, generations of human beings would be born, live, and then die on these ships. Even if that awkward arrangement could be made to work, how would everything else function for so long? What about the spacecraft? What about the AI?

Whether or not we have partial free will could soon be resolved by experiments in quantum physics, with potential consequences for everything from religion to quantum computers
