NASA’s Nancy Grace Roman Space Telescope is built to tackle two huge mysteries at once, dark energy’s cosmic push and the hidden diversity of exoplanets, using a sky sweeping camera and a planet imaging tech demo. Most us have had the same moment at...

A new observing technique has allowed scientists to identify carbon dioxide in the atmospheres of distant giant planets from Earth’s surface, offering a powerful alternative to space telescopes. More than 5,000 planets have now been confirmed beyond...

Astronomers have discovered a rare exoplanet orbiting in the opposite direction of its host star, challenging everything we know about planetary formation. Astronomers have uncovered a celestial oddity that defies the standard models of planetary...

Scientists used a novel technique on NASA data to uncover a previously hidden planet, revealing a world once thought out of reach. NASA’s TESS (Transiting Exoplanet Survey Satellite) has identified a distant exoplanet hidden in its archive by...

Planetary rotation could explain why some worlds turn into extreme greenhouse planets while others stay habitable. New research accepted by the Astronomical Journal highlights planetary rotation as a missing factor in the habitability equation,...

A new survey has identified 529 quiet, mature K dwarf “Goldilocks stars” near the Sun, offering the most stable radiation environments known and creating an unprecedented list of prime targets in the search for habitable exoplanets. For generations,...

NASA’s Roman Space Telescope moves into final Falcon Heavy integration, nine months early, aiming for an August launch. NASA’s Nancy Grace Roman Space Telescope is moving through a critical stage of its launch campaign at Kennedy Space Center, as...

The James Webb Space Telescope has captured a rare observation of an exoplanet that defies current scientific models, challenging our understanding of space. The James Webb Space Telescope (JWST) has detected ammonia in the atmosphere of HATS-6 b, a...

Astronomers have discovered a rare, ultra-dense mega-Earth 23 times the mass of our planet, offering new clues into the nature of exotic celestial bodies. Astronomers have identified a rare, high-density exoplanet that defies standard planetary...

Astronomers studying old NASA data have found signs of an Earth-sized planet circling a nearby star on a long, slow orbit, a rare discovery that hints at how common temperate rocky worlds may be. In 2017, NASA’s K2 space telescope was quietly watching...

Astronomers have detected auroral radio bursts from a gas giant 63 light-years away, enabling the first direct measurement of an exoplanet’s magnetic field. Astronomers have achieved a breakthrough in planetary science by detecting radio emissions...

NASA is developing a 99-meter starshade designed to block starlight, allowing ground-based telescopes to capture images of Earth-like rocky exoplanets. Detecting an Earth-like world remains one of the most formidable challenges in modern astronomy....

Researchers find that ultra‑high‑pressure mineral phases could solidify deep mantles on many super‑Earths, reshaping ideas of their interior structure. A recent investigation published in AGU Advances indicates that the innermost layers of many...

NASA’s upcoming Habitable Worlds Observatory aims to revolutionize the hunt for Earth‑like planets and extraterrestrial life beyond our solar system. NASA is outlining concepts for the Habitable Worlds Observatory, a cutting‑edge telescope intended to...

JWST has discovered that the giant exoplanet HATS-6 b is colder and chemically unique, challenging our current understanding of how planets form. The James Webb Space Telescope (JWST) has turned its gaze toward HATS-6 b, a peculiar giant exoplanet that...

A new study warns the James Webb Telescope might overlook hidden water on distant exoplanets, raising doubts about its detection limits. Mini‑Neptunes—planets a bit smaller than Neptune yet less dense than Earth—have long confounded astronomers because...

Astronomers have discovered a rare baby planet less than 1 million years old, providing a unique glimpse into the earliest stages of planetary formation. Astronomers have confirmed the existence of Elias 2-24 b, a massive infant world that currently...

New observations of Betelgeuse may finally uncover the long‑standing mystery surrounding the iconic red supergiant, shedding light on its behavior. A team of researchers using the European Southern Observatory’s Very Large Telescope (VLT) has captured...

Researchers have used a new AI algorithm to identify 44 promising star systems that could potentially host Earth-like planets for future study. Astronomers may have a powerful new tool in the search for Earth-like worlds, thanks to a machine-learning...

Geologists propose Venus once hosted massive oceans, challenging views of its ancient climate and habitability, hinting at past life potential. For many years Venus has been portrayed as a hostile world of crushing pressure, scorching temperatures and...
