How Perseid Meteors Trace a Journey from Comet to Night Sky
The Perseid meteor shower offers a glimpse into the solar system's ancient debris, as fragments from comet 109P/Swift-Tuttle enter Earth's atmosphere and produce visible streaks of light each August
Webb data links early red dots to UV-bright companions and black hole seeds
A new analysis of James Webb Space Telescope images suggests that compact 'little red dots' in the early universe may form near ultraviolet-bright companions, offering a possible route to the rapid birth of supermassive black holes
How the Heliosphere Shields the Solar System from Interstellar Space
Researchers are mapping the heliosphere, the vast bubble created by the solar wind that surrounds the Sun and planets, to understand how it protects the solar system from cosmic radiation and shapes planetary environments
Dark Energy Camera Reveals Star Formation in Corona Australis Cloud
The Dark Energy Camera has imaged the Corona Australis Molecular Cloud, capturing intricate details of a nearby star-forming region and highlighting the interplay of gas, dust, and young stars in one of the closest stellar nurseries to Earth
Atmosphere Detected on Rocky Exoplanet in Habitable Zone
Astronomers have directly detected helium in the atmosphere of LHS 1140 b, a rocky exoplanet orbiting within its star's habitable zone, using infrared spectroscopy. The finding raises new questions about atmospheric survival and planetary habitability.
Webb Telescope Detects Hidden Giant Planet in Beta Pictoris System
Astronomers have identified a third giant exoplanet in the Beta Pictoris system using the James Webb Space Telescope's spectroscopic capabilities, revealing a world previously concealed by the system's bright debris disk
Metasurface Grating Demonstrates Compact Solar Magnetic Field Mapping
A polarization-sensitive metasurface grating has matched conventional instruments in mapping solar magnetic fields, offering a route to smaller, simpler, and potentially more robust hardware for future space-based solar telescopes
NASA's IXPE Maps Magnetic Field of Unusual Pulsar in Milky Way
Astronomers have used NASA's Imaging X-ray Polarimetry Explorer to directly map the magnetic field around the pulsar PSR J1101-6101, revealing how high-energy particles stream through the Milky Way and testing long-standing theoretical predictions
Total Solar Eclipse and Perseid Meteor Shower Align on 12 August 2026
On 12 August 2026, a total solar eclipse will cross parts of Greenland, Iceland, and Spain, coinciding with the Perseid meteor shower and a prominent Venus. Observers in North America and Europe will experience rare overlapping astronomical events
Hidden White Dwarfs Detected Near Earth in Red Dwarf Binaries
Astronomers have identified four white dwarfs concealed by red dwarf companions within 65 light-years, using ultraviolet observations from the Hubble Space Telescope to reveal these elusive stellar remnants
