In the milky Way galaxy too much gas

24 April 1990, Shuttle discovery orbited our planet the Hubble space telescope, named after astronomer Edwin Hubble. Thanks to the work of Hubble, we know how to look like quasars, comets, distant planets of the Solar system and even galaxies. Recently on the NASA Hubble site appeared a press releasestating that data for 10 years of observations show that in the galaxy the milky Way has received more gas than out of it. The reason for this phenomenon remains a mystery to scientists. The study will be published in the journal Astrophysical Journal.

Perhaps our galaxy is stealing gas from their neighbors

What and how to see a space telescope?

Since the launch into Earth orbit of the space telescope Hubble has spent more than a million observations. Using two 25-foot solar panels, it receives energy from the sun and once a week sends about 120 gigabytes of data. The reason Hubble is in space, is that it enables scientists to record electromagnetic radiation in the infrared range. Due to the lack of influence of the atmosphere, the resolution of the telescope is 10 times the capacity of telescopes that are on Earth. Thus, in the analysis of the data Hubble collected over 10 years, astronomers have discovered an excessive amount of gas entering the milky way galaxy.

What do you think, why in our galaxy with more gas than it should be? Let's discuss this discovery astronomers in the comments and with members of our Telegram chat

The Cosmic Origins Spectrograph (COS) through the telescope, the gas is moving away from galaxy, it seems more red, and gas going to it seem more blue. This led to the unexpected realization that the amount of gas entering the milky way, much more than that which leaves our galaxy. Recall that after the Big Bang the universe was filled with gas, mostly hydrogen. Gradually the force of gravity is pulling the gas clouds from which later were born of the galaxy, and in galaxies of stars. Today, scientists believe that the supernova explosions eject gas from galaxies. In the vastness of space the gas cools, and then the gravity of the galaxy again pulls him inside. So in the galaxy and the formation of new stars.

The milky Way is a modest galaxy

Andrew Fox, an astronomer and lead author of the forthcoming study finds that our galaxy is pretty modest. Supernovae and strong stellar winds blow gas out of the disk of the galaxy, but this gas falls back into the galaxy, forming new generations of stars. However, the process — which took place over billions of years — does not explain why in our galaxy there is an excess of gas and not the balance. Experts suggest that one of the theoretical reasons underlying the unbalanced amount of gas in the milky Way galaxy, is the intergalactic medium — the mass of hydrogen gas that is believed to exist between different galaxies.

However, some experts believe that the milky way can use its gravitational pull to steal the gas reserves in the small nearby galaxies. Co-author of the study, Gopinath bordoloi Longman from the University of North Carolina believes that the original Hubble COS observations were made to explore the Universe far beyond our galaxy. However, scientists analyzed data on the amount of gas in the milky Way. The value of the archive of the Hubble space telescope is that scientists can use the same observations to explore both near and more distant Universe. Thus, the resolution of the Hubble allows astronomers to simultaneously study the local and remote celestial objects. According to experts, at the moment the milky Way is the only galaxy for which you can observe with a telescope.
