Hey @TeamYouTube, I have an unmonetized channel, but I've noticed ads playing on my videos. According to YouTube's policies, unmonetized channels shouldn't have ads. Can you please look into this and help resolve the issue? Thanks! #YouTube#UnmonetizedChannel#AdIssue@YouTube

@Ehsanism@StarTalkRadio@astrofalls Now, don't worry, this collision doesn't mean that the galaxies are expanding at different rates. The universe is actually expanding because of something called dark energy. It's a property of space itself that makes everything move away from each other.
@Ehsanism@StarTalkRadio@astrofalls But here's the really interesting part: scientists predict that in about 5 billion years, the Milky Way and Andromeda are going to collide. It's all because of gravity, which is what makes things with mass attract each other.
@Rainmaker1973 When the solar wind, a stream of charged particles that flows out from the sun, interacts with Earth's magnetic field, it can cause the oxygen atoms in the upper atmosphere to become excited. This excitation causes oxygen atoms to emit light in the specific spectrum.
@Rainmaker1973 Auroras typically appear in different shades of green, red, yellow, blue, and purple. The color of an aurora is determined by the type of gas particles that are present in the atmosphere and the altitude at which the aurora is formed.
@Rainmaker1973 Blue and purple:-
Blue and purple auroras are caused by nitrogen molecules in the upper atmosphere, and they are typically seen at lower altitudes, around 50 to 60 miles above the Earth's surface.
@Rainmaker1973 Green Auroras:-
Green auroras are caused by oxygen atoms that are located about 60 to 200 miles above the Earth's surface.
Red auroras:-
Red auroras are caused by oxygen atoms that are located higher up in the atmosphere, about 200 to 400 miles above the Earth's surface.
The telescope was launched into space on December 25, 2021, and is expected to provide unprecedented insights into the early universe and the formation of galaxies.
In December 2021, NASA's James Webb Space Telescope discovered a galaxy located 11.3 billion light-years away that is similar in size and shape to our own #MilkyWaygalaxy.

The James Webb Space Telescope is the largest and most powerful space telescope ever built, with a primary mirror that is nearly three times larger than that of its predecessor, the Hubble Space Telescope.
