10 strangest galactic phenomena that scare even experienced astronomers

(ORDO NEWS) — Unexpected galactic phenomena can equally surprise both beginners and the most experienced of astronomers.

They break predictions and confuse them, but they also add to our knowledge of how the universe works. The main thing is to look both ways and not miss them.

1- The Triangulum II Galaxy is a dwarf galaxy near the Milky Way, consisting of only a thousand stars. But it is quite capable of surprising – its stars move at an incredible speed. Perhaps due to the fact that a huge amount of dark matter is concentrated in Triangle II. Another option is due to the gravitational influence of neighboring galaxies.

2- The mysterious galactic ring is an object recently discovered by Hungarian and American astronomers. An object that shouldn’t exist.

It is unimaginably huge – five billion light-years wide (the Milky Way, for comparison – about 50 thousand sl), and emits the brightest gamma-ray bursts in the entire universe. It does not fit into any modern theory, and baffles scientists.

3- Tayna is the oldest and dimmest of all the galaxies found so far. It could only be detected in the distant cluster MACS J0416.1-2403 by combining the capabilities of Hubble and Spitzer, and was named the word in the language of the Aymara Indians – “first-born”. Presumably, it was formed only 400 million years after the Big Bang among the very first galaxies.

4- The birth of galaxies has always remained a purely theoretical area – until recently. Astronomers at the California Institute of Technology have discovered a protogalactic disk sucking hydrogen from a long filament of gas extending from a huge stellar structure. This spectacle was able to detect due to the successful location of two quasars, the light of which was reflected by the galactic “baby”.

5- The Large Magellanic Cloud and the Small Magellanic Cloud are the nearest neighbors of the Milky Way, and the Large, of course, is larger than the Small.

As it turned out, not just like that, because it was able to steal several million stars from its “brother”. Astronomers calculated this from the unusual speed characteristics of the red giants they observed, as well as their atypical chemical composition.

6- Hercules A is an outstanding galaxy for a number of reasons. Inside it lurked a black hole of monstrous mass, weighing 2.5 billion suns.

The black hole in the Milky Way weighs a thousand times less. From the center of Hercules A, two most powerful plasma jets fly out with a length of more than 1.5 million s.l. each emitting radio waves. This makes this galaxy the brightest source of radio waves known to man.

7- The oldest white dwarfs in the Milky Way were discovered quite recently, in the amount of 70 pieces. The Milky Way isn’t young in fact, it’s as old as the universe itself. And the white dwarfs found may have been the first stars in our galaxy, followed by hundreds of billions of others.

8- The brightest galaxy known to us was found using the WISE telescope. To say that WISE J224607.57-052635.0 glows is an understatement – it shines like 300 trillion suns.

The supposed reason is a black hole of such gravity that it is difficult to imagine its existence. It has long since exceeded its absorption threshold and spills energy into the surrounding dust cocoon, giving rise to a luminous aura.

9- Galaxy M60-UCD1 is quite small – only 300 light-years long and about 140 million stars. Only now its black hole easily plugs the black hole of the Milky Way – a mass of 21 million suns against 4 million.

It was previously believed that the mass of a black hole directly determines the size of a galaxy, but M60-UCD1 disproved this theory with its very existence.

10- At 13.2 billion years old, the EGS8p7 galaxy is so old that we shouldn’t be able to see it at all. By all indications, it should have been formed back in those days when the universe was filled with freshly created and impenetrable neutral hydrogen for the radiation of galaxies.

Perhaps it was so bright and hot that it reionized the hydrogen around it much earlier than other galaxies.

Galaxies tiny and huge, confirming existing hypotheses and destroying them into dust. Each such find is valued by scientists for its weight in gold, and is the subject of numerous disputes. Here are ten of the strangest galactic phenomena of recent years.
