How long is a light-year in Earth years? Since light travels at about 186,300 miles per second, with 86,400 seconds per day and about 365 days per year, that works out at about: 186300×86400×365≈5,875,000,000,000 miles. How long is 1 light-year in...
How long would it take us to travel 1 light-year? Even if we hopped aboard the space shuttle discovery, which can travel 5 miles a second, it would take us about 37,200 years to go one light-year. How long does it...
How many Earth years is a Lightyear? Coe et al. For most space objects, we use light-years to describe their distance. A light-year is the distance light travels in one Earth year. Is a light-year 365 days? A light year is...
How long would it take to travel 1 Lightyear? Light-year is the distance light travels in one year. Light zips through interstellar space at 186,000 miles (300,000 kilometers) per second and 5.88 trillion miles (9.46 trillion kilometers) per year. How long...

What is so special about Whirlpool Galaxy? They are actually long lanes of stars and gas laced with dust. Such striking arms are a hallmark of so-called grand-design spiral galaxies. In M51, also known as the Whirlpool galaxy, these arms serve...
Is there a black hole in Whirlpool Galaxy? Overall the galaxy is about 88% the size of the Milky Way. Its mass is estimated to be 160 billion solar masses, or around 10.3% of the mass of Milky Way Galaxy. A...
Is the Whirlpool Galaxy in the Milky Way? The Whirlpool (also known as Messier 51 (M51) is a two-armed spiral galaxy that lies somewhere between 25 to 37 million light-years away from our own Milky Way. How far is the Whirlpool...
How was the Whirlpool Galaxy discovered? The Whirlpool Galaxy was first discovered in 1773 by Charles Messier, who was charting the skies looking for objects that might be confused with comets. In 1845, astronomer William Parsons observed the galaxy pair with...
Does the Whirlpool Galaxy have planets? Using the change in brightness of an X-ray binary found in observations from two X-ray telescopes, scientists may have found an extragalactic planet. Scientists using the ESA’s XMM-Newton and NASA’s Chandra X-ray telescopes may have...
