7 weirdest stars in the universe

A star is a massive, glowing ball of gas that shines due to radiation from its internal energy sources. They are made up of mostly hydrogen, with some helium and other elements. They are born in clouds of gas and dust that contract under gravity. Stars generate energy through nuclear fusion in their cores, emitting light and heat that can be seen across vast distances. Each star possesses unique features, such as size, color, temperature, and brightness, which can vary significantly from one to another. Astronomers estimate that there are approximately 200 billion trillion stars in the observable universe. While all exhibit similar behaviors, some are known to be peculiar. Today we look at stars that challenge our perceptions of astrophysics and spark curiosity about the complex processes that govern the cosmos.

Przybylski's Star, also known as HD 101065, is a peculiar star in the constellation Centaurus located About 356 light-years from the Sun. It is known for its unusual spectrum and chemical composition. It was discovered by Polish-American astronomer Antoni Przybylski in 1961. The star is said to be rich in rare-earth elements and some radioactive elements, which we don't normally see in stars.

Tabby's Star, also known as KIC 8462852, is a star in the constellation Cygnus that has been the subject of much scrutiny due to its unusual brightness dips. It is located 1,200 light years away from the sun and is about 1.4 times the mass of the Sun. The dips are different from those caused by planets crossing between the star and Earth,

PSR J1719-1438 b is a gas giant exoplanet that orbits a K-type star, and was discovered in 2011. PSR J1719-1438b and its planet is a combination of a pulsar and a planet. 1438b is a planet that has a mass that is nearly the same as Jupiter's. Scientists believe that 1438b is the remnant of a star whose outer layer was stripped off by the more massive pulsar, leaving behind an object made of carbon. This object hence can’t be categorized as a planet or any other object yet.

HD140283— or Methuselah was discovered in 2000 and is considered the oldest star in the universe. It was about 14.4 billion years old. It is a second generation star, and is a topic of wonder as the universe itself is 13.8 billion years old, so how can a star be older than the universe?

HE 0437-5439 is some 30 million years old, and is moving at a speed of 1,600,000 mph. Scientists believe that this star was formed near the center of the Milky Way, however due to an interaction with the black hole at the center of our galaxy, Sagittarius A, it was thrown astray out of our galaxy into interstellar space.

Vega is the fifth brightest star in the night sky and the brightest star in the constellation Lyra. It's located in the northern hemisphere and is visible from northern Canada, Alaska, and most of Europe. However it exhibits weird behavior, which causes it to be squashed and have a dark halo. Vega's rapid rotation of once every 12.5 hours stretches it into an egg-like shape called an oblate spheroid.

The star HV 2112 was first cataloged as a variable star in 1908 by astronomer Henrietta Swan Leavitt. At the time, astronomers thought it was a red supergiant that was dying and about to go supernova. However it was later found that it is a rare type of star that's a combination of a red supergiant and a neutron star. It has high levels of elements like lithium, calcium, and rubidium.
