ESO VLT investigates rocky exoplanets orbiting a distant star

Astronomers have been using the Very Large Telescope at the European Southern Observatory to observe exoplanets orbiting a distant star called L 98-59. Astronomers observed the L 98-59 system because it and its exoplanets resemble those in the inner solar system. One of the interesting discoveries resulting from the observations is of a rocky exoplanet with half the mass of Venus.

A quartet of exoplanets has been discovered orbiting a pair of young stars

A quartet of exoplanets has been discovered orbiting a pair of young stars

A team of international astronomers has used NASA's TESS spacecraft to identify four exoplanets that are orbiting a pair of related young stars. The stars are called TOI 2076 and TOI 1807. Astronomers believe the exoplanets could provide details on a little-understood stage of planetary evolution. Planets in both systems are in a transitional or teenage phase of their lifecycle.

Scientists discover a third transiting exoplanet orbiting a distant star

Scientists discover a third transiting exoplanet orbiting a distant star

The ESA has an exoplanet-hunting satellite in orbit called CHaracterising ExOPlanet Satellite or CHEOPS. Scientists were investigating a pair of previously known planets orbiting around a distant star when they unexpectedly saw a third exoplanet transit the star. The transit observed will reveal details about the strange planet researchers on the project described as being "without a known equivalent."

Radio signals coming from the nightside of exoplanets could reveal planetary details

Radio signals coming from the nightside of exoplanets could reveal planetary details

So far, in the search for exoplanets, scientists have been unable to detect radio signals coming from those planets. However, they believe that radio signals from distant solar systems could give astronomers valuable information about the characteristics of the planet they emanate from. A research paper published by Rice University scientists has outlined a better way to determine which exoplanets are most likely to produce detectable radio signals based on activity within the magnetosphere on the nightside of the planet.

Geology expertise helps scientists find Earth-like planets

Geology expertise helps scientists find Earth-like planets

University of British Columbia geologist Brendan Dyck has leveraged his expertise in planetary formation to help scientists identify exoplanets that might support life. Astronomers have so far identified more than 4000 exoplanets, with others waiting for confirmation. Some of those planets are orbiting stars in what is believed to be the habitable zone and could sustain life. Dyck is using the geology of early planet formation to help identify exoplanets that might be capable of supporting life.

Hubble watches exoplanet PDS 70b grow as it gathers gas and dust

Hubble watches exoplanet PDS 70b grow as it gathers gas and dust

The Hubble Space Telescope is watching an exoplanet called PDS 70b as it gathers mass in its distant star system. NASA says that the exoplanet is gathering gas and dust slowly as the world builds mass over millions of years. Researchers have been able to use Hubble to directly measure the mass growth rate of PDS 70b for the first time using the space telescope's ultraviolet sensitivity to capture radiation created by extremely hot gas falling onto the planet.

Evidence of tectonic activity discovered on an exoplanet for the first time

Evidence of tectonic activity discovered on an exoplanet for the first time

Astronomers have been intently studying an exoplanet called LHS 3844b for many years. Back in 2019, researchers announced that they believed the planet was covered by dark lava rock. Researchers studying the exoplanet have now made another exciting discovery with evidence for the first time of tectonic activity on another planet.

Astronomers discover a new rocky planet in the Virgo constellation

Astronomers discover a new rocky planet in the Virgo constellation

Astronomers have discovered a new rocky planet in the Virgo constellation that could be the best chance yet for studying the atmospheres of such planets outside of our solar system. The planet is known as Gliese 486b and is classified as a super-Earth. That means it's a rocky planet larger than Earth but smaller than ice giants such as Neptune and Uranus.

High school students discover a quartet of exoplanets

High school students discover a quartet of exoplanets

A group of high school students have possibly become the youngest astronomers to make a major discovery ever. The students published findings this week as part of a research mentorship program from the Center for Astrophysics at Harvard and the Smithsonian. The students discovered a five-planet system around TOI-1233 that includes a super-Earth planet that have the potential to help solve mysteries about planet formation.

Gas-giant exoplanet WASP-107b has a surprisingly low core mass

Gas-giant exoplanet WASP-107b has a surprisingly low core mass

Researchers have been studying a gas-giant exoplanet called WASP-107b. During the study, they discovered the exoplanet's core mass is much lower than what was previously believed to be necessary to build up the immense gas envelope surrounding gas-giant planets. Research conducted by the Université de Montréal suggests that gas-giant planets may form more easily than previously believed.

Scientists have identified one of the oldest planetary systems ever discovered

Researchers have identified what they say is one of the oldest planetary systems that has ever been discovered. The planetary system has a rocky planet known as TOI-561b orbiting a star that is 10 billion years old. That star is more than twice as old as the sun, and researchers say it shows planets have been forming since the early days of the universe.

Researchers believe solar flares on distant stars could help detect life

Researchers believe solar flares on distant stars could help detect life

Scientists around the world are searching the universe for exoplanets in an attempt to find life outside the earth. It was once thought that distant stars with frequent solar flares could mean any orbiting planets were devoid of life. A new study has found that robust stellar flare activity might not prevent life on exoplanets. The robust flare activity could help us detect life.
