Who discovered radio waves from Center of Milky Way?

Jansky
While hunting for radio static for Bell Labs, Jansky made the surprise discovery of radio waves coming from the center of our Milky Way Galaxy. In this photo, he is standing under a rough map of the night sky and pointing to the constellation of Cassiopeia.

Are there radio waves in space?

Radio emission is common in the universe. They’re generated by everything from planets and stars, exotic objects like pulsars and black holes, galaxies, and, of course, human technology. This week (October 12, 2021), astronomers said they’ve detected new and unusual radio wave signals, unlike any found before.

What is beyond our galaxy?

A new study gives the first evidence that exoplanets exist beyond the Milky Way. After all, our galaxy is a warped disc about a hundred thousand light-years across and a thousand light-years thick, so it’s incredibly difficult to see beyond that. But now, a new study is saying there could be extragalactic exoplanets.

Which star population is very old and is metal poor?

Extreme Population II stars
They are relatively old stars, with ages ranging from 2 – 14 billion years. Extreme Population II stars (the most metal poor) are found in the halo and the globular clusters; these are the oldest stars.

Is Sun a third generation star?

Our Sun, by any metric, is at least a third-generation star, but is probably made up of a variety of materials that have existed in multiple generations of stars of unequal properties.

When did first galaxy formed?

billion to 14 billion years ago
Observations by Hubble Space Telescope and ground-based instruments show that the first galaxies took shape as little as one billion years after the Big Bang, which probably took place about 13 billion to 14 billion years ago. There are two leading theories to explain how the first galaxies formed.
