Astronomers Tally the Growing Carbon Footprint of Space Science

Next-generation ground-based observatories will be enormous, such as the Extremely Large Telescope, which will eclipse the size of the Colosseum in Rome when it is completed in 2024.Now some researchers are thinking about the carbon footprint of modern astronomy and realizing that they, like everyone else, might have to consider alternative ways of doing business in order to keep climate-warming emissions in check.

A Strange Radio Signal Was Just From Earth, Not Aliens

Last fall, a colleague of Sofia Sheikh’s posted a message in her group’s Slack channel, where members of the Breakthrough Listen Search for Extraterrestrial Intelligence (SETI) collaboration talk about the radio telescope signals they’re analyzing for possible signs of communications from space.

Astronomers Track a Fast Radio Burst to Its Source—a Magnetar

Unlike CHIME, which looks at small chunks of the sky at any given time, Caltech’s Survey for Transient Astronomical Radio Emission 2 (STARE2) telescope observes the entire sky at once, which allowed the Caltech team to quickly confirm that the burst was extremely powerful.

Spies Can Eavesdrop by Watching a Light Bulb's Vibrations

They say it allows anyone with a laptop and less than a thousand dollars of equipment—just a telescope and a $400 electro-optical sensor—to listen in on any sounds in a room that's hundreds of feet away in real-time, simply by observing the minuscule vibrations those sounds create on the glass surface of a light bulb inside.

Space Photos of the Week: Hubbub Over Hubble

We are entering low earth orbit this week and spending time with the Hubble Space Telescope.The veil nebula is a supernova remnant of a star that died a mere 8,000 years ago and was more than 20 times the mass of our Sun. When stars like this go supernova, they give off a massive shockwave pulse that pushes material out at astronomical speeds.

“So the detailed observations of the middle corona that we make at eclipses will remain unique for the foreseeable future.” He adds that the new telescope also can’t generate wide-field views the way smaller telescopes can during eclipses—allowing for study of the farthest reaches of the coronal footprint—nor can it match the resolution of the instrumentation on the Solar and Heliospheric Observatory now in orbit around Earth.
