It has an apparent magnitude of NGC is a spiral galaxy located at around million light-years away. It is around 75, light-years across, having spiral arms yet no ring. Bright blue areas of star formation can be observed in its spiral arms. This galaxy is part of the Eridanus Group of galaxies.
NGC is a spiral galaxy located at around 60 million light-years away from us. A couple of supernovas have been observed here. The constellation of Eridanus contains one of the biggest supervoids ever discovered, nicknamed the Eridanus Supervoid or Great Void. It is estimated to be a region quite devoid of galaxies, that stretches between million to 1 billion light-years, and between 6 to 10 billion light-years away.
Some believe that the void may be due to quantum entanglement between our universe and another. However, recently, two meteor showers have been discovered, the Nu Eridanids, and the Omicron Eridanids. The Omicron Eridanids peak between November 1 and Eridanus Constellation.
Home » Stars » Eridanus Constellation. The Nu Eridanids and Omicron Eridanids are now the official first meteor showers associated with the constellation. The brightest star in Eridanus is Achernar, a blue main-sequence star that has an apparent magnitude of 0.
Achernar is also the ninth brightest star in the night sky, it is also a binary star. The primary star, Achernar A, is the least spherical star in the Milky Way ever studied. Currently, around 32 stars in Eridanus have been discovered to host planets. The constellation of Eridanus hosts a supervoid, designated as the Eridanus Supervoid — it is the second-largest known void.
Around 13 stars from Eridanus are within Location The constellation of Eridanus is the 6 th largest constellation in the sky. Right Ascension: 3. Notable Stars Several notable stars are located in the constellation of Eridanus, such as Achernar, Cursa, Acamar, 39 Eridani, 40 Eridani, p Eridani, or Ran which hosts a planet very similar to Jupiter.
It now turns out that, in addition to the confirmed planet s that astronomers think are orbiting the star, there is a dust disk, likely created by collisions of planetesimals in the recent past. There are also two belts of rocky asteroids orbiting the star at distances of 3 and 20 astronomical units.
An astronomical unit is a distance between Earth and the Sun. There are also debris fields around the star, leftovers indicating that planetary formation did indeed take place at Epsilon Eridani. Epsilon Eridani is an interesting star in its own right, even without its planets. At less than a billion years old, it's very youthful. It's also a variable star, which means that its light varies on a regular cycle.
In addition, it shows a lot of magnetic activity, more so than the Sun does. That higher rate of activity, along with its very fast rotation rate That's practially a newborn in star years, and explains why there's still a detectable debris field in the area.
It's not likely there's life on this star's known world, although astronomers once speculated about such life signaling us from that area of the galaxy. Epsilon Eridani has also been suggested as a target for interstellar explorers whenever such missions are finally ready to leave Earth for the stars. In , a microwave survey of the sky, called Project Phoenix, searched for signals from extraterrestrials that might inhabit various star systems.
Epsilon Eridani was one of its targets, but no signals were found. This star has been used in many science fiction stories, TV shows, and films. Something about its name seems to invite fabulous stories, and its relative closeness suggests that future explorers will make it a landing target. Epsilon Eridani is central in the Dorsai!
