The Sun emitted a strong solar flare, peaking at 7:14 p.m. ET on July 2, 2023. NASA’s Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event. Solar flares are powerful bursts of energy. Flares and solar... Continue Reading →
What if you could see out to the edge of the observable universe? You would see galaxies, galaxies, galaxies, and then, well, quasars, which are the bright centers of distant galaxies. To expand understanding of the very largest scales that humanity can see, a... Continue Reading →
A new AI-based approach for controlling autonomous robots satisfies the often-conflicting goals of safety and stability. In the film “Top Gun: Maverick,”Maverick, played by Tom Cruise, is charged with training young pilots to complete a seemingly impossible mission — to... Continue Reading →
A study carried out by a research team from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), the Catalan Institute of Nanoscience and Nanotechnology (ICN2), University of Exeter Centre for Graphene Science, and TU Eindhoven demonstrates that graphene-based materials can be used to efficiently convert high-frequency signals into...

Have you seen the bird in the Milky Way? Beyond the man in the Moon, the night sky is filled with stories, and cultures throughout history have projected some of their most enduring legends onto the stars and dust above. Generations of people... Continue Reading →
The jellyfish galaxy JO206 trails across this image from the NASA/ESA Hubble Space Telescope, showcasing a colorful star-forming disk surrounded by a pale, luminous cloud of dust. A handful of foreground bright stars with crisscross diffraction spikes stands out against an... Continue Reading →
The center of the Lagoon Nebula is a whirlwind of spectacular star formation. Visible near the image center, at least two long funnel-shaped clouds, each roughly half a light-year long, have been formed by extreme stellar winds and intense energetic starlight. A tremendously bright nearby star, Herschel 36,... Continue Reading →
"I have often wondered why Red is the color of love, and of the heart. Until I realized that red is also the color of blood, pain, fire, and all that is dangerous and sacred. Thus Red is both beautiful... Continue Reading →
Phosphorus, a key chemical element for many biological processes, has been found in icy grains emitted by the small moon and is likely abundant in its subsurface ocean. Using data collected by NASA’s Cassini mission, an international team of scientists has... Continue Reading →
