Can a galaxy have two stars?
For the first time ever, scientists have seen a double-star system in another galaxy emitting gamma-rays, the most energetic form of light. The discovery was made by NASA’s Fermi Gamma-ray Space Telescope.
What does Andromeda galaxy look like in the sky?
The single most important thing you need to see the galaxy is a dark sky. What does the galaxy look like to the eye? Assuming you have a dark sky, it appears as a large fuzzy patch – bigger than a full moon in the sky – but vastly fainter and more subtle.
Can the earth survive Andromeda collision?
Astronomers estimate that 3.75 billion years from now, Earth will be caught up amid the largest galactic event in our planet’s history, when these two giant galaxies collide. Luckily, experts think that Earth will survive, but it won’t be entirely unaffected.
Can planets collide?
Planets evolve over billions of years, as bits of dust and gas clump together. However, planetary formation can be easily disrupted by impacts from other celestial objects. Such collisions can cause a wide range of consequences for young planets, such as atmospheric loss, the 3D simulations suggest.
What would happen if two suns?
Other scientists suggest that day and night would have completely different meanings on an Earth with two suns. When both suns were up, days would be much brighter. Nights would be different too because the suns would sometimes set at different times [source: Warren].
Where is Andromeda in the sky tonight?
Andromeda is up in the fall sky. To find it, locate the constellation Andromeda on a sky chart, and then find it in the sky. It is near the great square of Pegasus. The location of the Andromeda galaxy in relation to the constellation is marked on the charts found here.
Will the moon eventually crash into the Earth?
Long answer: The Moon is in a stable orbit around Earth. There is no chance that it could just change its orbit and crash into Earth without something else really massive coming along and changing the situation. The Moon is actually moving away from Earth at the rate of a few centimetres per year.
What is the Andromeda Galaxy?
The Andromeda Galaxy, which is currently on a gradual collision course with the Milky Way Galaxy, can be spotted in the sky. It is one of the brightest astronomical objects visible to the human eye.
What is the relationship between Andromeda and the Milky Way?
Andromeda and Milky Way in context. The Andromeda galaxy and our Milky Way galaxy reign as the two most massive and dominant galaxies within the Local Group of Galaxies. The Andromeda Galaxy is the largest galaxy of the Local Group, which, in addition to the Milky Way, also contains the Triangulum Galaxy and about 30 other smaller galaxies.
What does the Andromeda Galaxy look like with binoculars?
You’ve just landed on the Andromeda galaxy, which looks like a smudge of light to the unaided eye. If you can’t see the Andromeda galaxy with the eye alone, by all means use binoculars. The Great Andromeda Nebula, photographed in the year 1900. At this point, astronomers couldn’t discern individual stars in the galaxy.
How do you find the Andromeda Galaxy without a telescope?
The Andromeda Galaxy is the only major galaxy that you can see without any optical aids. Under dark, Moon-free skies, your unaided eye should be able to find the Andromeda Galaxy as a faint misty patch a short distance from the band of the Milky Way.
