What is the weirdest star in the universe?
When HD 140283, a sub-giant star 190 lightyears from Earth, was first studied in the 1950s it posed something of a paradox: it appeared to be 16 billion years old – two billion years older than the Universe itself.
What is the rarest star in space?
An O-type star is a hot, blue-white star of spectral type O in the Yerkes classification system employed by astronomers. They have temperatures in excess of 30,000 kelvin (K).
What is a bizarre star?
A bizarre star may have its origins in one of the most energetic events in the cosmos. Astronomers have found that a star with a very unusual composition may have formed in the wake of a new type of hypernova – a stellar explosion with 10 times the energy of a supernova.
What is the strangest galaxy in space?
The galaxy, called AGC 114905, is located some 250 million light-years away from Earth and is about as large as the Milky Way. This distant galaxy, however, contains a thousand times fewer stars than our galactic home.
What is the weakest star in the universe?
The smallest known star right now is OGLE-TR-122b, a red dwarf star that’s part of a binary stellar system. This red dwarf the smallest star to ever have its radius accurately measured; 0.12 solar radii.
What is the most rare thing in the universe?
He designed a rocking horse made of 24-carat gold. Scientists have spotted the “rarest event ever recorded”, in a major breakthrough as part of attempts to solve a dark matter mystery.

What is a star made of in space?
Stars are huge celestial bodies made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores. Aside from our sun, the dots of light we see in the sky are all light-years from Earth.
How big is a strange star?
For masses between 1 solar mass and 2 solar masses, the radii of strange stars are about 10 km, as for neutron stars. Strange stars may have an exposed quark surface, which is capable of radiating at rates greatly exceeding the Eddington limit, but has a low emissivity for X-ray photons.
What is beyond Milky Way galaxy?
Although several dozen minor galaxies lie closer to our Milky Way, the Andromeda galaxy is the closest large spiral galaxy to ours. Excluding the Large and Small Magellanic Clouds, visible from Earth’s Southern Hemisphere, the Andromeda galaxy is the brightest external galaxy you can see.
What’s the weirdest star in the sky?
But also hiding inside this southern sky constellation, just beyond what our eyes can see, is a truly weird star. Przybylski’s Star, or HD 101065, is about four times the mass of the sun.
What are the oddballs hiding in our sky?
Hiding in our sky are a few stellar oddballs worth seeking out. These stars aren’t your run-of-the-mill balls of hydrogen and helium. They seem to play by their own rules, standing out among their neighbors as true eccentrics, unapologetic in their uniqueness.
Is this the first TZO star ever discovered?
HV 2112 (which is either in the Milky Way or in our neighbor dwarf galaxy, the Small Magellanic Cloud) seems to have all these hallmarks, which would make it the first TZO ever discovered. Mira can sometimes be one of the fainter stars in Cetus. Other times, it’s one of the brightest stars in the sky.
Is Betelgeuse the brightest star in Orion?
The bright star Betelgeuse, which forms the shoulder of the constellation Orion (The Hunter), is about 11 times more massive than the sun but 900 times more voluminous. That bloated condition shows that Betelgeuse is near death, which will come in the form of a violent supernova explosion.
