Not Like Venus Or Mars, Distant Exoplanet May Have Atmosphere Like Earth's
A distant exoplanet might have an atmosphere similar to Earth's, early observations from the James Webb Space Telescope (JWST) suggest. It is part of a group of planets orbiting a star called TRAPPIST-1, about 40 light-years away from Earth.

Astronomers Capture Sharpest-Ever Solar Flare Images with NSF’s DKIST Telescope
Astronomers have achieved a major breakthrough by capturing the sharpest images of a solar flare ever recorded, using the National Science Foundation’s Daniel K. Inouye Solar Telescope (DKIST). Observed at the hydrogen-alpha wavelength during the decay of an X1.3-class solar flare, the images unveiled hundreds of ultra-fine coronal loops averagin...

James Webb Telescope Detects Methanol and Ethanol Near Young Stars, Hinting at Life’s Origins
NASA’s James Webb Telescope has identified ethanol and methanol isotopes around protostars and HD 100453. These discoveries offer valuable clues about the cosmic origins of life, indicating that comets filled with organic molecules might have seeded early Earth.

JWST Captures Unseen Details of Exoplanets in HR 8799 and 51 Eridani Systems
The James Webb Space Telescope (JWST) has captured groundbreaking images of exoplanets in the HR 8799 and 51 Eridani systems. By modifying its coronagraphs, astronomers allowed more starlight to pass through, revealing clearer planetary details. The study, published in The Astrophysical Journal Letters, highlights the first successful detection of ...

Aditya-L1’s SUIT Telescope Captures First-Ever Solar Flare Kernel, Revealing Unseen Solar Activity
India’s Aditya-L1 mission has achieved a historic milestone with its Solar Ultra-violet Imaging Telescope (SUIT) capturing the first-ever solar flare kernel in the near-ultraviolet spectrum. This unprecedented observation confirms energy transfer across different layers of the Sun's atmosphere, advancing the understanding of solar flares and spac...

Study Finds Coronal Loop Flickers Could Predict Solar Flares Hours in Advance
NASA's Solar Dynamics Observatory has revealed a potential breakthrough in predicting solar flares. Scientists observed brightness fluctuations in coronal loops—plasma structures in the Sun's atmosphere—that intensify hours before solar flares occur. This discovery, with a prediction accuracy of 60–80%, may provide 2–6 hours of advance warn...

Aditya-L1 Records Coronal Mass Ejection, Reveals New Details on Solar Plasma Movement and Magnetic Activity
Aditya-L1, India’s first solar mission, observed a Coronal Mass Ejection on July 16, 2024. Researchers found that the event caused significant coronal dimming, increased turbulence, and solar plasma deflection due to magnetic fields. These insights, derived from VELC measurements, deepen our understanding of solar activity and its space weather i...

Study Explains Blinking Gamma-Ray Bursts Using Falling Stardust, Unsteady Jets
Astrophysicists have developed the first 3D simulation of the entire evolution of a jet from its birth by a rotating black hole to its emission far from the collapsing star. Simulation explains that as the star collapses, its material falls on the disk that swirls around the black hole. This falling material tilts the disk, and, in turn, tilts the ...

Astronomers May Have Discovered a Black Hole Candidate Through Gravitational Microlensing
A team of astronomers from the University of California, Berkeley, has discovered what appears to be a free-floating black hole for the first time using gravitational microlensing. The unseen compact object's mass is estimated to be between 1.6 and 4.4 times that of the Sun, according to the astronomers.

Closest 'Potentially Habitable' Planet Found 14 Light Years Away
Astronomers have discovered the closest potentially habitable planet found outside our solar system, orbiting a star just 14 light years away.

These Baby 'Monster' Galaxies Are Swaddled in Dark Matter
Scientists have discovered a nursery full of monstrous cosmic babies. In a study published Friday in the Astrophysical Journal Letters, researchers report nine so-called monster galaxies - ones bursting with rampant star formation - from the early days of the solar system.

Sun Can Produce 'Superflares' That May Disrupt Life on Earth
Sun has the potential to produce superflares, with energy equivalent to a billion megaton bombs, which may severely disrupt power grids and communication systems on the Earth, a new study has found.
