Newly Discovered Earth-sized Planet Orbits Ultra-cool Red Dwarf Star: A Significant Step Towards Understanding Habitability in the Universe's Last Light
An Earth-sized planet named SPECULOOS-3 was discovered orbiting an ultra-cool red dwarf star.
SPECULOOS-3 is located about 55 light years away from Earth and takes around 100 times less luminosity than the Sun.
The discovery of SPECULOOS-3 represents an important step in understanding these enigmatic stars and their planetary systems.
The discovery was made using the transit method and took approximately 17 hours for the planet to complete an orbit.
Ultra-cool red dwarf stars are expected to be the last ones still shining in the universe when all other stars have burned out.
An Earth-sized planet named SPECULOOS-3 has been discovered orbiting an ultra-cool red dwarf star. This discovery was made by the SPECULOOS project, which uses a network of robotic telescopes worldwide to search for rocky planets around ultra-cool dwarf stars. The planet takes approximately 17 hours to complete an orbit around its star and is located about 55 light years away from Earth. The ultra-cool red dwarf star, which is more than twice as cold as our sun, ten times less massive, and a hundred times less luminous than the Sun, poses a unique challenge for astronomers due to its faintness. However, the discovery of SPECULOOS-3 represents an important step in understanding these enigmatic stars and their planetary systems. The discovery was made using the transit method, which involves observing the dimming of starlight as a planet passes in front of its host star. This method has been successful in discovering many exoplanets to date, including those around ultra-cool dwarf stars like SPECULOOS-3. The discovery of this Earth-sized planet around an ultra-cool red dwarf star is significant because these stars are expected to be the last ones still shining in the universe when all other stars have burned out. The long lifespan of these stars means that planets orbiting them may be habitable for longer periods than those around shorter-lived stars. However, the harsh radiation environment around SPECULOOS-3 makes it unlikely that an atmosphere exists on the planet. Despite this challenge, scientists are eager to learn more about this new discovery and what it can tell us about the potential habitability of planets orbiting ultra-cool red dwarf stars.
An Earth-size planet named SPECULOOS-3 has been discovered orbiting an ultracold red dwarf star.
The discovery was made by the SPECULOOS project located at the Paranal Observatory in Chile.
Accuracy
An Earth-size planet named SPECULOOS-3 has been discovered orbiting an ultracool red dwarf star.
Red dwarfs are believed to account for 70% of the stars in the Milky Way galaxy and have exceptionally long lifetimes.
SPECULOOS-3 b is likely tidally locked to its star, meaning it has an eternal dayside and an everlasting nightside.
Red dwarfs are not well understood due to their low luminosity and it is rare to discover planets around them.
The discovery of SPECULOOS-3 marks a step in the right direction toward understanding red dwarf worlds.
SPECULOOS-3 b receives about 16 times more radiation than Earth and is not habitable.

]An illutsration of the exoplanet SPECULOOS-3 orbiting its red dwarf star. (Image credit: NASA/JPL-Caltech)[] Astronomers have discovered an Earth-size planet orbiting an ultracool red dwarf star similar in size to Jupiter. The red dwarf, located some 55 light-years away, is 100 times less bright than the sun and exhibits half the temperature of our star.[...]
A new Earth-sized planet, Speculoos-3b, was discovered orbiting a small, cool star.
The planet's year is shorter than an Earth day.
Researchers detected the planet as it passed in front of its host star, causing a dimming in starlight.

. . . the same side, called the day side, always faces the star, just like the moon does for the Earth. On the other hand, the night side would be locked in endless darkness.
In such an environment, the presence of an atmosphere around the planet is highly unlikely.
An international team of astronomers has detected a new Earth-sized planet named SPECULOOS-3 b, which is around 55 light years away from us.
The planet orbits an ultra-cold red dwarf star that is more than twice as cold as our sun, ten times less massive, and a hundred times less luminous.
SPECULOOS-3 b takes approximately 17 hours to complete an orbit around its star.
The discovery was made by the SPECULOOS project, which is led by the University of Liège in Belgium and uses a network of robotic telescopes worldwide.

. . . the same side—the "dayside"—always faces the star in a relationship similar to our moon and Earth.
The discovery, published in Nature Astronomy, was made by the SPECULOOS project . . .
While most astronomical data is automatically analyzed and planetary candidates are often first detected by algorithms before being reviewed by humans, in this case it did not happen. Members of the SPECULOOS team had begun to quickly glance at the nightly data when they became available, and Dr. Georgina Dransfield . . . noticed the planetary signal.

Ultracool dwarf stars are widespread in the solar neighbourhood but their extremely low luminosity has left their planetary population largely unexplored.
Our galaxy is home to over 70% M dwarfs, also known as red dwarfs, which are cool and dim compared to the Sun but burn for 100 billion years or more.
An international team using robotic telescopes spotted an Earth-sized planet orbiting an ultra-cool red dwarf star that is about 55 light-years from Earth.
The exoplanet, SPECULOOS-3 b, takes about 17 hours to orbit its star and is thought to be tidally locked with the same side always facing the star.
Ultra-cool dwarf stars are unexplored due to their faintness, but the SPECULOOS project was designed specifically to explore them for rocky planets.
The SPECULOOS-3 star is thousands of degrees cooler than our Sun with an average temperature of about 4,760 F (2,627 C), but it pummels its planet with radiation, meaning there’s likely no atmosphere.
SPECULOOS-3 b receives almost 16 times more energy per second than Earth receives from the Sun.
The planet shares its name with the spiced shortbread SPECULOOS, both hailing from Belgium.
