Astronomers recently mapped the rarest type of galaxy ever found: an elliptical galaxy sporting rings of young stars. Most galaxies, including our own Milky Way, are spiral or elliptical. But this recently mapped galaxy, called PGC 1000714, is unique.
in fact, Why was there probably no life in the galaxy 12 billion years ago?
There were no heavy elements. Why was there probably no life in the galaxy 12 billion years ago? Orbiting at a perfect balance.

indeed What is the rarest planet? Known as GW Orionis (or GW Ori) and located about 1,300 light-years from Earth, the system is a rare example of a triple-star solar system, with two suns orbiting one another at the center, and a third star swirling around its siblings from several hundred million miles away.
What is the rarest item in the universe?
Interstellar object Oumuamua may be one of the rarest in the universe. Scientists say the First, a gigantic space object that came from outside our solar system, can actually be extremely rare. According to them, it is a huge piece of hydrogen ice.

Is the Milky Way dying?
Actually, the Milky Way may have died at least once around 7 billion years ago; it revived after a period of 2 billion years, during which a whole bunch of stars died, going supernova and ejecting their outer envelopes into space, filling the galaxy with material for making new stars.
What is older than the universe?
One such datum is the existence of a star with an age reported to be older than the cosmos itself. This star is called the Methuselah star, named after the biblical patriarch.
Are there any first generation stars left?
Astronomers using the NASA/ESA Hubble Space Telescope have found no evidence of hypothetical first-generation stars — called Population III stars — as far back as when the Universe was just 500 million years old. An artist’s impression of the early Universe.
Which is hotter capella or Sun?
Capella Ab is hotter but dimmer, being 72.7 ± 3.6 times brighter than the sun, and having a surface temperature of around 5.730 ± 60 K. They are very dim, Capella H has 0.05 the sun’s luminosity and around 0.54 solar radii. To be more accurate, both stars have a combined visual luminosity around 1% that of our sun.
What star shines the brightest at night?
Bottom line: Sirius is the brightest star in the night sky as seen from Earth and is visible from both hemispheres. It lies just 8.6 light-years away in the constellation Canis Major the Greater Dog.

Do we have 2 suns?
But does it even make sense that there could be two suns? … The idea of a second sun in our solar system is not as bizarre as it might sound. Binary star systems (two stars orbiting the same center of mass) are quite common. In fact, Alpha Centauri, our solar system’s nearest neighbor, is a binary system.
What planet rains diamonds?
Deep within Neptune and Uranus, it rains diamonds—or so astronomers and physicists have suspected for nearly 40 years. The outer planets of our Solar System are hard to study, however. Only a single space mission, Voyager 2, has flown by to reveal some of their secrets, so diamond rain has remained only a hypothesis.

What is the hardest thing in universe?
Summary: A team of scientists has calculated the strength of the material deep inside the crust of neutron stars and found it to be the strongest known material in the universe.
Is wood rarer than diamond?
but wood is a complex organic structure and compared to its diamonds is simple. In the whole universe, wood is rarer than diamonds. Trees can give you oxygen and it is one of the major member of our ecosystem and after they die they gives us wood. So woods are more valuable than diamonds.
What is the hardest thing to find in the world?
“At” stands for astatine. It is an element with 85 protons packed into its nucleus, thus the atomic number “85” … The problem is, there’s something about 85 protons in a tight space that nature doesn’t enjoy.
What happens if 2 galaxies collide?
The merging of galaxies will radically affect their shape. For example, two spiral galaxies can merge and form an elliptical galaxy. Sometimes even more than two galaxies can collide with each other. … Merging galaxies can also trigger the creation of new stars.
Will humans ever leave the Milky Way?
Our Galaxy, the Milky Way, is a disk of stars about 100,000 light-years across, and about 1,000 light-years thick. … So, to leave our Galaxy, we would have to travel about 500 light-years vertically, or about 25,000 light-years away from the galactic centre.
Will the Milky Way galaxy exist forever?
Four billion years from now, our galaxy, the Milky Way, will collide with our large spiraled neighbor, Andromeda. The galaxies as we know them will not survive. In fact, our solar system is going to outlive our galaxy.
What is the oldest thing on Earth?
Microscopic grains of dead stars are the oldest known material on the planet — older than the moon, Earth and the solar system itself.
What is the oldest planet known?
At 12.7 billion years old, planet Psr B1620-26 B is almost three times the age of Earth, which formed some 4.5 billion years ago. This exoplanet, the oldest ever detected in our Milky Way galaxy, has been nicknamed “Methuselah” or the “Genesis planet” on account of its extreme old age.
How old is the youngest star?
That means the neutron star would be a millennial, no older than 33. If confirmed, it would be the youngest neutron star known to mankind, as Astronomy reports. To date, the youngest supernova remnant is the 330 years old Cassiopeia A, about 11,000 light-years away from Earth inside the Milky Way.
Is the Sun a 1st generation star?
Astronomers assert that the sun is not a first-generation star because of the presence of heavy elements. Among astronomers, elements heavier that hydrogen and helium are labeled metals. … The sun has been found to be comparatively metal-rich, meaning that it is at least a second-generation star.
What color were the first stars?
After about 400 million years the first stars began to appear, and new light appeared. Brilliant blue-white stars. As stars and galaxies appeared and evolved, the cosmos began to take on a new color.
What is the biggest star?
The cosmos is full of objects that defy expectations. Although it’s difficult to pin down the exact traits of any given star, based on what we know, the largest star is UY Scuti, which is some 1,700 times as wide as the Sun.
