The Breakthrough Listen search for intelligent life is, to date, the most extensive technosignature search of nearby celestial objects. We present a radio technosignature search of the centers of 97 nearby galaxies, observed by Breakthrough Listen at the Robert C. Byrd Green Bank Telescope. We performed a narrowband Doppler drift search using the turboSETI pipeline with a minimum signal-to-noise parameter threshold of 10, across a drift rate range of $\pm$ 4 Hz\ $s^{-1}$, with a spectral resolution of 3 Hz and a time resolution of $\sim$ 18.25 s. We removed radio frequency interference by using an on-source/off-source cadence pattern of six observations and discarding signals with Doppler drift rates of 0. We assess factors affecting the sensitivity of the Breakthrough Listen data reduction and search pipeline using signal injection and recovery techniques and apply new methods for the investigation of the RFI environment. We present results in four frequency bands covering 1 -- 11 GHz, and place constraints on the presence of transmitters with equivalent isotropic radiated power on the order of $10^{26}$ W, corresponding to the theoretical power consumption of Kardashev Type II civilizations.

Let’s not send a few thousand people to Mars as a big experiment in survival.

The authors of the book in the article, Kelly and Zach Weinersmith, were also on an episode of Factually. Between this article and that episode, I'm pretty down on any cool scifi future in space.

Today, ESA's Gaia mission releases a goldmine of knowledge about our galaxy and beyond. Among other findings, the star surveyor surpasses its planned potential to reveal half a million new and faint stars in a massive cluster, identify over 380 possible cosmic lenses, and pinpoint the positions of more than 150 000 asteroids within the Solar System.

An annular solar eclipse, also known as a “ring of fire” eclipse because of the way the sun and moon line up, will be visible in the US, Central America and South America on 14 October

Modern solar panels can harness not just ultraviolet light, but also visible and in some cases infrared. But all of these designs are built to harness the sun, which gives off most of its light in the green range and emits plenty of ultraviolet light. But most exoplanets orbit red dwarf stars, which have a peak brightness in the red or infrared and emit little ultraviolet.

If we want to visit nearby planetary systems, such as the Proxima Centauri system, then we'll need to have solar panels capable of harnessing red dwarf starlight.

In 2009 a giant star 25 times more massive than the sun simply vanished. OK, it wasn't quite that simple. It underwent a period of brightening, increasing in luminosity to a million suns, just as if it was ready to explode into a supernova. But then it faded rather than exploding. And when astronomers tried to see the star using the Large Binocular Telescope (LBT), Hubble and the Spitzer space telescope, they couldn't see anything.

NASA's OSIRIS-REx sample collection from asteroid Bennu exceeded expectations in material quantity, slowing the curation process. Advanced analysis methods are underway, with a more detailed examination planned for the coming weeks. The initial curation process for NASA’s OSIRIS-REx sample of ast

Southwest Research Institute scientists are using telescopes to observe the asteroid Psyche in the infrared, providing context for NASA's upcoming Psyche mission. Dr. Stephanie Jarmak is using the James Webb Space Telescope (JWST) to look for water signatures on the metallic surface of Psyche, while Dr. Anicia Arredondo is using some of the last data collected by the Stratospheric Observatory for Infrared Astronomy, or SOFIA, to study differences in Psyche's composition at different points on its surface.

Study reveals how magma oceans may affect the evolution of hot exoplanets. Lava worlds, massive exoplanets home to sparkling skies and roiling volcanic seas called magma oceans, are distinctly unlike the planets in our solar system. To date, nearly 50% of all rocky exoplanets yet discovered ha
