What’s the weather like at night on Venus? Scientists are finally finding out.
Just one planet away, Venus is relatively close to Earth and we have been studying it for a long time, with the first Venusian probe reaching the planet in 1978. However, scientists have known very little about what the weather is like at night on Venus. That is, until now.
As the United States looks beyond war in Afghanistan and Iraq, the military is preparing for conflict in new domains, from outer space to cyberspace.

Researchers recently tested whether a balloon-borne sensor could listen for venusquakes to learn about the planet’s makeup.
A new image hints at the cosmic fate of the Milky Way.
Astronomers on the Hubble Team captured a three-way tug of war between galactic siblings as their gravitational force pulled on one another.

The NASA team is considering renaming its new groundbreaking telescope due to anti-LGBTQ+ claims involving its honoree James Webb.
Engineers usually regard heat as “waste energy” since it is hard to efficiently turn into anything useful. However, a new class of thermoelectric materials could change that after researchers opted to try the exact opposite of the usual approach. A paper in Science Advances explains why, speeding the search for even better versions.
As the name suggests, thermoelectric materials turn heat into electricity, skipping the boiling water stage used in most bulk electricity production. However, cost and inefficiency have kept thermoelectric generators restricted to niche applications, such as powering spacecraft like the Mars Perseverance rover where lightweight, reliable energy production matters more than price.
Thermoelectric materials are too expensive and polluting for more widespread use, but new versions that replace heavier elements with magnesium could change that, opening the door to even better options that could find widespread uses.
The image shows an elongated galaxy sandwiched, and stretched, between two galaxies. A long tail is visible in the galaxy on the right in this image: Called a “tidal tail,” this can occur when stars and gases are “stripped” from the outside arms of galaxies during a merger, according to Cosmos.

The Hubble Space Telescope — the size of a large school bus — is over 30 years old. The solar-powered telescope takes detailed images of far-off cosmic objects, like Arp 195, yet the legendary instrument is wearing down with age, most recently exemplified by a computer problem that sent Hubble offline for weeks. Still, NASA expects “Hubble will last for many more years and will continue making groundbreaking observations, working in tandem with other space observatories including the James Webb Space Telescope to further our knowledge of the cosmos.”
Particle accelerators are hugely important in the study of the matter of the Universe, but the ones we think of tend to be gigantic instruments – surrounding cities in some cases. Now scientists have made a much smaller version to power an advanced laser, a setup that could be just as useful as its larger counterparts.
The particle accelerator in question is a plasma wakefield accelerator, which generates short and intense bursts of electrons, and the laser it’s powering is what’s known as a free-electron laser (FEL), which uses its light to analyze atoms, molecules, and condensed matter in incredibly high resolutions.
While this scenario has been tried before, the resulting laser light hasn’t been intense enough to be useful at smaller scales. Here, the researchers were able to keep the setup enclosed in few normal-sized rooms while amplifying the final electron beam produced by the laser, increasing the intensity by 100 times in the last step of the process.
