Astronomers Identify an Exoplanet That Acts like a Mirror

The discovery of LTT9779 b not only sheds light on the fascinating behavior of exoplanets but also presents a celestial puzzle. The planet belongs to a rare category known as "ultra-hot Neptunes," as it is unusually large for its location so close to the star.

Astronomers Discover Two Super-Earths Orbiting a Star Nearby

Using NASA's Transiting Exoplanet Survey Satellite (TESS), a group of astronomers were able to discover two super-Earths that revolve around a nearby red dwarf known as TOI-2095 within its habitable zone.

Astronomers Spotted a Star Swallowing Its Planet for the First Time

The Sun will swallow the three closest planets to it (Mercury, Venus, and Earth) when it enters the red giant stage in about five billion years. According to scientists, this observation gave the first real idea of how this engulfment occurs.

NASA's Webb Telescope Spots Dust Storms on a Distant Exoplanet

Researchers proved that its swirling clouds are made up of silicate particles, ranging from tiny specks to small grains. The temperature of the atmosphere reaches 830 degrees Celsius (1,500 degrees Fahrenheit).

Space

Astronomers Find a New Potential Habitable Exoplanet 31 Light-Years Away

The planet, named Wolf 1069 b, is located in the habitable zone of its star, a red dwarf. A habitable zone is an area where conditions are suitable for the existence of liquid water on the surface, which means that the planet can hypothetically sustain life.

Astronomers Discover an Earth-Sized Planet Within Its Star's Habitable Zone

Planets located outside the solar system are called exoplanets. The Earth-like planet, dubbed TOI 700 e, is the fourth exoplanet to be discovered orbiting the small, cool dwarf star TOI 700.

Astronomers Discovered Two Exoplanets That May Be Mostly Water

Scientists hope the planets orbiting the red dwarf Kepler-138 won't be the last of its kind to be discovered. As instruments and detection techniques improve, more aquatic worlds like Kepler-138c and Kepler-138d are likely to be discovered.

NASA's Webb Studied the Atmosphere of an Alien Exoplanet in Detail

The planet's atmosphere is composed of sulfur and silicates. When they interact with the parent star's light, they produce sulfur dioxide – this is the first time such a compound has been found in the atmosphere of an exoplanet.

Astronomers Predicted the Death of an Exoplanet

Kepler-1658b is a typical hot Jupiter. It orbits a pro-evolved star of spectral class F, located 2,600 light-years from Earth. The exoplanet has six times the mass of Jupiter, and its orbit is only 0.05 AU (7 million km) from its parent luminary.

NASA Shared the First Detailed Image of a Planet Outside Our Solar System

The exoplanet is located about 385 light years from Earth, and, according to various estimates, it is 6-12 times larger than Jupiter and is between 15 million and 20 million years old.

Space

Scientists Discover a Super-Earth Located Near Its Star's Habitable Zone

A super-Earth class exoplanet 4 times the mass of Earth was detected orbiting within the habitable zone of a red dwarf dubbed Ross 508. The star is located in the constellation Serpens and is five times smaller than our Sun.

TESS Discovers Two Rocky Exoplanets Orbiting a Red Dwarf

During a series of observations, TESS recorded regular changes in the brightness of HD 260655, caused by the transits of two exoplanets, designated HD 260655 b and HD 260655 c. Astronomers were then able to confirm the existence of these rocky exoplanets.

Jupiter's Twin Was Spotted 17,000 Light-Years Away

This is the first time in the history of science that the telescope has been able to detect an extrasolar planet through a microlensing event. Kepler wasn't really designed for such observations.

Astronomers Discover Two Saturn-Mass Exoplanets

The discovery was made using the radial-velocity method within the CARMENES survey. The essence of the method is to find the characteristic "wobbles" of stars caused by the gravity of their invisible companions.
