When it comes to skin cancer , a major risk factor is prolonged exposure to ultraviolet UV radiation. Understanding the basics about UV radiation and how it damages your skin is an important first step in learning how to safeguard yourself against skin cancer. The good news is that the danger posed by UV radiation can be greatly reduced by you! Yes, you can still enjoy outdoor activities while limiting your skin cancer risk by taking simple, smart protective measures. UV radiation is part of the natural energy produced by the sun. Tanning beds also emit UV radiation.

[Trick] Effect of Rotation of Mirror on Reflected Ray - Reflection of Light - Ray Optics The Effect Of A Light Ray Reflecting

Sparked by an image uploaded to Twitternew research indicates that the light produced by black hole accretion may be bright enough to reflect off of dust, illuminating the host galaxy, and creating light and dark rays similar to the effect of crepuscular rays on Earth. The research is published in The Astrophysical Journal Letters. When a supermassive black hole accretes, or "feeds," on the matter surrounding it, the resulting release of energy gives off an intense light. Until now, scientists believed that this light only illuminates the parts of a galaxy that fall within narrow ionization cones. But photographic evidence of IC —a radio-loud Seyfert galaxy with an active galactic nucleus AGN —indicates that the light, or rays—which scientists liken to the crepuscular rays cast by clouds that obscure the sun near sunset—may be Te enough to reflect off of nearby dust, illuminating most of the galaxy, causing shadows from the black hole ring, or dark rays, in between.

Using images from the Hubble Space Telescope, the team focused in on IC and its torus—an unseen ring of cool, dusty gas surrounding the here hole—which might be the source of the light and its rays.

If Tue torus is big enough it becomes unstable, the gravity and rotation holding it together point one direction near the black Reflectiing and in a different direction as influences from the galaxy start to become important. This looks like a warp or a bend," said Maksym. The Effect Of A Light Ray Reflecting, it's showing us something that is hard, and usually impossible, to see directly. This could have implications for anybody trying to understand the behavior of supermassive black holes and their environments.

Unlike most scientific research, the team observing IC 's strange rays assembled in a peculiar fashion: via crowd sourcing on social media. In Decemberspace image processing expert and citizen scientist Judy Schmidt noticed strange cones while processing an image of ICat first wondering if they were real, and if they were, whether they were galaxy-sized shadows, star streams, or something else.

I couldn't see them in the archive thumbnails or the preview of the stretched image in FITS Liberator," said Schmidt, adding that when she first saw what appeared to be shadows, she thought, "That's not possible is it? This is an active galaxy with a supermassive black hole in the middle. Is it casting galaxy-sized shadows?

Or are those just star streams? It didn't take long for Maksym and other scientists to notice the tweet and start making conjectures, which eventually led to the formation of the research team and the discovery.

In December, she noticed some 'dark rays' extending from the nucleus of the galaxy IC and Tweeted to her followers asking if they might be anything interesting," said Maksym, whose interest was immediately piqued since he was already working on the same galaxy from a different scientific angle. When you read the Twitter thread, you can see how the ideas unfolded in real-time, and transformed into this really unusual research. This is a project that is just begging for new data because it raises more questions than it answers.
