Sun Science: How the sneaky nature of ultraviolet light works

ROCHESTER, NY (WROC) – Being exposed to harmful ultraviolet (UV) rays from the sun is the reason we get sunburned from time to time. FUN FACT: Did you know that while UV rays are invisible to humans, some insects such as bumblebees can see them? UV rays sourced from the sun are subdivided into different … Read more

Creepy Optical Illusion Makes It Look Like a Black Hole Is Coming to Get You

A new optical illusion can trick most of us into perceiving an expanding black hole, new research reports. The image is completely static, but researchers say it gives people “a growing sense of darkness, as if entering a space voided of light”. The illusory forward motion is probably our mind’s way of preparing us for … Read more

Dying Early Universe Galaxies Could Be Killed by Their Supermassive Black Holes

The Milky Way galaxy isn’t very active, as far as galaxies go. Every year, it produces around three to four Suns’ worth of new stars in the entirety of its spiral body, and stars of all ages can be found sprinkled throughout. But there are some galaxies even quieter – elliptical galaxies, for which most … Read more

The flame-like objects are the comet’s fragments and their tails, while the dusty comet trail is the line bridging the fragments. Credit: NASA Astronomers are … Read more

A New Quantum Technique Could Change How We Study The Universe

There’s a revolution underway in astronomy. In fact, you might say there are several. In the past ten years, exoplanet studies have advanced considerably, gravitational wave astronomy has emerged as a new field, and the first images of supermassive black holes (SMBHs) have been captured. A related field, interferometry, has also advanced incredibly thanks to … Read more

Astronomers Have Found a Super-Earth Near The Habitable Zone of Its Star

The very tiny motion of a small star has revealed the presence of a super-Earth exoplanet, orbiting at a distance that is close to habitable. Around a faint red dwarf called Ross 508, located just 36.5 light-years away (yet too dim to be seen with the naked eye), astronomers have confirmed the existence of a … Read more
