Milky Way galaxy larger than initially thought scientists say

Our dwelling galaxy – the Milky Way – is a big, spiral galaxy, which based on Nasa is made up of roughly 100 billion stars.

Earth is positioned alongside one of many galaxy’s lengthy, curved spiral arms, round midway from the centre.

A workforce of scientists used information from the European Space Agency’s XMM-Newton and Nasa’s Chandra X-ray house telescopes to take a more in-depth have a look at three shiny cosmic explosions referred to as gamma-ray bursts.

These are amongst a few of the brightest explosions identified to happen within the universe, and happen in galaxies far past our Milky Way.

However, scientists have been capable of monitor the sunshine given off from these gamma-ray bursts as they bounced off mud clouds within the spiral arms of our galaxy.

They have been then capable of work out precisely how far-off the mud clouds have been – which in flip helped reveal the space to the outer elements of the Milky Way.

The workforce discovered that two of the Milky Way’s spiral arms could also be extra distant from the centre of the galaxy than beforehand thought – by as much as 10%.

That signifies that the Milky Way might be barely bigger than earlier maps steered.

Experts say the findings might assist them enhance their understanding of the Milky Way, and that additional analysis might construct an much more detailed image of our dwelling galaxy.
