SETI Live ·

2024/05/21

T Coronae Borealis, or T CrB, is a well-studied nova system in the constellation Corona Borealis. In fact, T CrB produces a recurring nova — one of only five known in our galaxy — that erupts approximately every 80 years, making this a once-in-a-lifetime event. Astronomers predict that the star will explode again within the coming year, likely before this September. When it does erupt, the rather dim T CrB could become as bright as our North Star. Observers with the SETI/Unistellar Network have been

In a groundbreaking discovery, astronomers have identified an Earth-sized planet closer and younger than any previously known. Positioned remarkably close to both our planet (73 light-years away) and a Sun-like star, this newly found world offers a unique opportunity for scientists to study the evolution of planets. Catalogued as HD 63433 d, this hot exoplanet orbits its star in 4.2 days, making it one of the closest orbiting Earth-sized worlds. With its young age and proximity, HD 63433 d promises

2024/04/30

A deeply eroded giant volcano, active from ancient through recent times and with possible remnants of glacier ice near its base, had been hiding near Mars’ equator in plain sight. Its discovery points to an exciting new place to search for life, and a potential destination for future robotic and human exploration. “We were examining the geology of an area where we had found the remains of a glacier last year when we realized we were inside a huge and deeply eroded volcano,” said Dr. Pascal Lee,

A potential future space mission known as the Large Interferometer for Exoplanets (LIFE) could study terrestrial worlds in their stars' habitable zones (where water can be liquid) using spectral emissions in the mid-infrared. With only one known example of a world with life - Earth - scientists recently examined whether or not such a mission could determine if a planet was habitable. Published in The Astrophysical Journal, the results of a recent study concluded that yes, LIFE could find "signatures

The TRAPPIST-1 planetary system has fascinated both scientists and the public since the discovery of the last five of its seven terrestrial worlds in 2017. With four of those planets in the so-called habitable zone, where water can be liquid, the system has become a favorite target of ground- and space-based telescopes alike, especially with regard to the potential for harboring life. However, TRAPPIST-1 is a red dwarf star, cooler and smaller than our own Sun, leading to concerns about the ability

Only eight times in history have scientists found an asteroid, tracked its trajectory toward Earth, and caught the resulting fireball on cameras. The latest of these eight events happened in January 2024, with the discovery of asteroid 2024 BX1, a mere three hours before impacting the atmosphere over Europe. And of course, the SETI Institute's own Dr. Peter Jenniskens was hot on the trail, flying to Germany to help search for meteorite fragments. Within the week, several pieces were discovered, and

Throughout human history, comets have fascinated us. They have gone from signs and portents of bad things to come to well-studied and even visited "dirty snowballs". Every year, observers search the skies, hoping to discover the Next Big Comet - Halley, Hyakutake, Hale–Bopp, McNaught. From SOHO and LINEAR to ATLAS and IRAS, numerous observatories have continued to add to the count of discovered comets.
