An ultra-faint collection of 1,000 stars orbiting the Milky Way is the most lightweight galaxy ever discovered, scientists say. The dwarf galaxy known as Segue 2 is bound together by a tiny clump of dark matter.
Which galaxy is the smallest?
The smallest independent structures known today are Segue 1 and Segue 3. Only approximately 1000 stars are present in the entirety of dwarf galaxies Segue 1 and Segue 3,…
How long would it take to get to Andromeda?
How long would it take to get to the Andromeda Galaxy? Forget it! Although it may be one of the closest galaxies to our own, since the Andromeda Galaxy is 2.5 million light years distant it would take 2.5 million years to get there if (and it’s a huge ‘if’) we could travel at the speed of light.
How many light years is the smallest galaxy?
It is inside one of the densest galaxies known to date — the M60-UCD1 dwarf galaxy that crams 140 million stars within a diameter of about 300 light-years, which is only 1/500th of our galaxy’s diameter.
What are the biggest galaxies?
Largest galaxy: IC 1101
Our Milky Way galaxy is around 100,000 light-years across, but that’s fairly average for a spiral galaxy. In comparison, the largest known galaxy, called IC 1101, is 50 times larger and about 2,000 times more massive than our galactic home.

What are the 4 types of galaxies?
In 1936, Hubble debuted a way to classify galaxies, grouping them into four main types: spiral galaxies, lenticular galaxies, elliptical galaxies, and irregular galaxies.
Will Voyager 1 leave the Milky Way?
Thousands of years from now, Voyager 1 and Voyager 2 will leave our solar system. But their instruments will stop working long before that happens. Voyager 2, looking back. In 1977, NASA launched the twin Voyager spacecraft to probe the outer reaches of our solar system.
How far away is the closest galaxy to ours?
The closest known galaxy to us is the Canis Major Dwarf Galaxy, at 236,000,000,000,000,000 km (25,000 light years) from the Sun. The Sagittarius Dwarf Elliptical Galaxy is the next closest , at 662,000,000,000,000,000 km (70,000 light years) from the Sun.
How fast is the Milky Way moving towards Andromeda?
The Andromeda Galaxy is approaching the Milky Way at about 110 kilometres per second (68 mi/s) as indicated by blueshift.
What is the oldest galaxy in the universe?
They deduced the target galaxy GN-z11 is not only the oldest galaxy but also the most distant. It’s so distant it defines the very boundary of the observable universe itself.
Can humans travel to another galaxy?
The technology required to travel between galaxies is far beyond humanity’s present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.
What galaxy do we live in?
The Milky Way is a large barred spiral galaxy. All the stars we see in the night sky are in our own Milky Way Galaxy. Our galaxy is called the Milky Way because it appears as a milky band of light in the sky when you see it in a really dark area.
What is the heaviest thing in the universe?
So massive stars become neutron stars – the heaviest things in the universe – and even more massive stars become black holes.
What is the most dangerous thing in the universe?
Death by black hole
Black holes are expected to form when a massive star dies. After the star’s nuclear fuel is exhausted, its core collapses to the densest state of matter imaginable, a hundred times denser than an atomic nucleus. That’s so dense that protons, neutrons and electrons are no longer discrete particles.
What’s bigger than the Galaxy?
The Milky Way is big, but some galaxies, like our Andromeda Galaxy neighbor, are much larger. The universe is all of the galaxies – billions of them! NASA’s telescopes allow us to study galaxies beyond our own in exquisite detail, and to explore the most distant reaches of the observable universe.
