Do photons wear out? An astrophysicist explains light’s ability to travel vast cosmic distances without losing energy

The speed of light is the fastest anything can travel. What happens to a photon from a galaxy 25 million light years away on its journey toward Earth?

Telescope team reads the fine print — from more than a kilometre away

A pair of telescopes picking up reflected light achieve a performance 14 times better than a single telescope can manage alone. A pair of telescopes picking up reflected light achieve a performance 14 times better than a single telescope can manage alone.

Do photons wear out? An astrophysicist explains light’s ability to travel vast cosmic distances without losing energy - Tech and Science Post

My telescope, set up for astrophotography in my light-polluted San Diego backyard, was pointed at a galaxy unfathomably far from Earth. My wife, Cristina, walked up just as the first space photo streamed to my tablet. It sparkled on the screen in front of us. “That’s the Pinwheel galaxy,” I said. The name is derived from its shape – albeit this pinwheel contains about a trillion stars. The light from the Pinwheel traveled for 25 million years ac…

Close-up: 'Candyfloss' Clouds of Large Magellanic Cloud Dwarf Galaxy

Close-up: 'Candyfloss' Clouds of Large Magellanic Cloud Dwarf Galaxy | HubbleThis NASA/European Space Agency Hubble Space Telescope picture features a sparkling cloudscape from one of the Milky Way’s galactic neighbors, a dwarf galaxy called the Large Magellanic Cloud. Located 160,000 light-years away in the constellations Dorado and Mensa, the Large Magellanic Cloud is the largest of the Milky Way’s many small satellite galaxies.This view of du…

Hubble Captures Stunning Image of Incline Spiral Galaxy NGC 3511 Located 43 Million Light-Years from Earth

The Hubble Space Telescope, a powerful camera in space run by NASA and ESA, took an incredible photo of a galaxy called NGC 3511. This galaxy, tilted at a cool 70-degree angle, looks like a glowing spiral in the sky, almost like a cosmic Vincent van Gogh painting that grabs your attention. First, the basics: [...]
