Astronomers Detect Methane in the Atmosphere of the Nearest T Dwarf Star to Earth
Astronomers have detected methane in the nearest known T dwarf, offering new insight into its atmospheric composition. The study further highlights that the carbon abundance in the planet is estimated to be -1.5 dex, while the effective temperature could be around 1,000 K. The author of the paper further revealed that the low metallicity of the T ...

Two New Exoplanets Found Orbiting a Star in Draco Constellation
Astronomers have identified two exoplanets, TOI-1453 b and TOI-1453 c, orbiting a star 250 light-years away in Draco. The planets, a super-Earth and a sub-Neptune, were detected using NASA’s TESS satellite and the HARPS-N spectrograph. TOI-1453 b is a rocky planet orbiting close to its star, while TOI-1453 c is twice Earth’s size and may have a...

Scientists Observe Rare Plastic Ice, A Hybrid Form of Ice and Water, Under Extreme Pressure and Heat
Researchers have observed plastic ice, a phase where water molecules rotate while staying in a solid structure. The discovery, made under extreme pressure and heat, could provide new insights into the composition of icy exoplanets and moons. The findings suggest plastic ice VII may have existed in Europa and Titan's interiors and could influence nu...

A Neptune-Like Exoplanet Is Racing Through Space at Record Speed
Scientists have detected an exoplanet racing through space at 1.2 million mph, making it the fastest known planet. The Neptune-sized world orbits a hypervelocity star, first hinted at in 2011 via gravitational microlensing. Astronomers, using Keck Observatory and Gaia data, have confirmed the system’s extreme speed, suggesting it may even leave t...

Astronomers Spot a High-Speed Star That May Carry a Planet With It
Astronomers have identified a celestial object moving through the Milky Way at over 1.2 million mph. Believed to be a small star with a possible massive exoplanet, the discovery could mark the fastest-known planetary system. If its speed exceeds 1.3 million mph, it may eventually escape the galaxy. Scientists are still verifying whether it is the s...

A Star With a Planet May Be Racing Through the Galaxy at Record Speed
Astronomers have identified a potential record-breaking exoplanet system moving at 1.2 million mph. Detected through microlensing, the discovery suggests a low-mass star with an orbiting planet is racing through the Milky Way. Data from the Keck Observatory and ESA’s Gaia satellite indicate a high-speed celestial body that may eventually escape t...

Newly Confirmed Super-Earth HD 20794 d May Support Life in Habitable Zone
A super-Earth, HD 20794 d, has been confirmed within a habitable zone 20 light years from Earth. The planet, first detected in 2022, has a mass six times that of Earth and orbits a sun-like star. Although its elliptical orbit affects temperature stability, its potential to sustain liquid water makes it a key target for upcoming space missions. Scie...

NASA's TESS Discovers Fastest Disintegrating Planet Ever Seen: What You Need to Know
NASA’s TESS has observed the closest and fastest disintegrating planet, BD+05 4868 Ab, located 141 light-years away. The planet loses a moon’s mass every million years as it is bombarded by its host star. Scientists are examining its massive dust trails, offering rare insights into the composition of terrestrial exoplanets. Researchers from MIT...

Astronomers Discover Water and Carbon Dioxide in WASP-166 b's Atmosphere
Astronomers have detected water and carbon dioxide in the atmosphere of WASP-166 b, a hot super-Neptune exoplanet. Using data from the James Webb Space Telescope (JWST), the findings also noted ammonia in smaller quantities. WASP-166 b, located 368 light-years away, is a massive planet that orbits its star every 5.44 days, with a temperature of 1,2...

New Study Challenges Planet Formation Models with PDS 70b’s Chemical Mystery
A new study on PDS 70b, a forming exoplanet located 400 light-years away, reveals a significant mismatch between its atmospheric composition and the surrounding protoplanetary disk. This discovery casts doubt on existing planet formation models, suggesting that more research is needed to understand how planets gather materials and elements during t...

Venus Never Had Oceans or Conditions to Support Life, New Study Finds
Scientists from the University of Cambridge have concluded that Venus likely never had oceans or conditions to support life. Their study, published in Nature Astronomy, analysed atmospheric chemistry and volcanic activity. They found that volcanic gases lacked significant steam, indicating the planet's interior has always been dry. This research ha...

NASA's James Webb Space Telescope Discovers Fourth Planet in Kepler-51 System
A study published in The Astronomical Journal reveals the discovery of Kepler-51e, the fourth planet in the Kepler-51 system, led by Dr Jessica Libby-Roberts of Penn State and Dr Kento Masuda of Osaka University. Observations indicated that only a four-planet model could explain the transit timing variations. Kepler-51e’s orbit, just inside the s...

Indian Scientists Discover A Massive Exoplanet That is Five Times Larger Than Earth
Indian scientists have identified a new exoplanet named TOI-6651b, which is five times larger than Earth and has a mass around 60 times greater. Located in the Neptunian desert, it orbits a Sun-like star every 5.06 days. The planet's composition suggests unique evolutionary processes, providing valuable insights into how such dense exoplanets form ...
