Sgr A*, at the heart of the Milky Way and clocking in at 4.3 million solar masses, is the closest supermassive black hole we have access to. It's also on the quiescent end of the activity scale, which ...

The Space Coast set a new record in 2024 with 93 launches from all providers, building off the 72 orbital missions flown in 2023. With SpaceX’s continued pace, more launches from United Launch ...

A powerful X1.8 solar flare erupted on January 4, 2025, and was recorded at its peak—7:48 a.m. ET—by NOAA’s Solar Ultraviolet Imager (SUVI). Such intense flares have the potential to disrupt Earth’s ...

Q: I need help deciding whether to put solar film on my west-facing windows in the Seattle area, and, if so, whether the film ...

In 1998, a photo taken from the International Space Station showed a black, oddly shaped object which became known as the Black Knight. What was it?

Scientists have warned that Earth is well overdue for a solar 'superflare' - a stellar explosion containing the energy of billions of atomic bombs.

About 13 billion light-years away there is a supermassive black hole actively sending out a spectacular beam of energy directly towards Earth. Interestingly, this isn't just any black hole; it's a ' ...

EM radiation can have any wavelength, from radio waves hundreds of meters long to gamma rays spanning just a few picometers (trillionths of a meter). And there’s a tiny sliver of this range ...

Optics and photonics covers the entire electromagnetic spectrum from high-energy gamma rays and X-rays ... to long-wavelength microwave and radio waves.

Using NASA's Fermi space telescope, Italian astronomers have observed a radio source known as 3C 216. As a result, they ...

Furthermore, the astronomers analyzed multiwavelength data of 3C 216, finding simultaneous flaring activity in optical, ultraviolet, X-ray and gamma-ray bands between May 1–9, 2023.
