Can The Universe Be Older Than We Think? Can the universe be older than we think? XMM-Newton Is the universe older than we thought? The map results suggest the universe is expanding more slowly than scientists thought, and is 13.8 billion years old, 100 million years older than previous estimates. How accurate is the age
How Fast Will The Jwst Travel? After separating from its launch vehicle, JWST began to slow rapidly and it is now traveling at a cruising speed of around 0.2 miles per second towards L2, or roughly 720 miles per hour. How far is JWST from Earth? Now, the observatory will live in perpetuity at a
Can You See Milky Way With Eyes? Can you see Milky Way with eyes? Up, down, left, right, that is the Milky Way. From Earth, it can be seen as a hazy form of stars in the night sky that the naked eye can barely notice. You can see the Milky Way all year, no
How Fast Is The Sun Traveling Through Space? The sun and the solar system appear to be moving at 200 kilometers per second, or at an average speed of 448,000 mph (720,000 km/h). Even at this rapid speed, the solar system would take about 230 million years to travel all the way around the Milky
Can We Reach The Edge Of The Universe? Can we reach the edge of the universe? As far as we can tell, there is no edge to the universe. Space spreads out infinitely in all directions. Furthermore, galaxies fill all of the space through-out the entire infinite universe. This conclusion is reached by logically combining
How Fast Does The Spitzer Telescope Travel? Originally, Spitzer’s camera designers had hoped the spacecraft would detect galaxies about 12 billion light-years away. In fact, Spitzer has surpassed that, and can see even farther back in time – almost to the beginning of the universe. How fast is the Hubble telescope moving? Hubble travels at
Do Irregular Galaxies Have A Halo? Do irregular galaxies have a halo? They have a bulge and halo, like spiral galaxies, but don’t have the flat disk of stars. The stars in ellipticals tend to be older. Irregular galaxies have no identifiable shape or structure to them. They are often chaotic in appearance, without a
Do Any Constellations Contain Galaxies? Do any constellations contain galaxies? Both terms constellation and galaxy are related to stars, but constellations are not real objects while galaxies are. Constellations are imaginary patterns. A galaxy, on the other hand, is made up of gas, dust, billions of stars, and their solar systems. What constellations have galaxies
Could Life Exist In A Globular Cluster? Could life exist in a globular cluster? Brighter stars also live shorter lives, and since globular clusters are old, those stars have died out. [That means that the] predominant stars in globular clusters are faint, long-lived red dwarfs. Any potentially habitable planets they host would orbit nearby and
Do Galaxies Spin Clockwise? Do galaxies spin clockwise? About half of all spiral galaxies appear to be rotating clockwise and the other half counterclockwise. The direction a galaxy rotates depends on your perspective. As an analogy, consider a spinning bicycle wheel. When you look at a spinning wheel from one side, it looks like it’s
