RS Ophiuchi (RS Oph) is a recurrent nova system approximately 5,000 light-years away in the constellation Ophiuchus. In its quiet phase it has an apparent magnitude of about 12.5. It has been observed to erupt in 1898, 1933, 1958, 1967, 1985, 2006 and 2021 and reached about magnitude 5 on average.
What star went nova?
On August 8, 2021, the star RS Ophiuchi burst into view in Earth’s sky as what astronomers call a nova. It’s a rare nova visible to the unaided eye. It’s nowhere near as bright as the brightest stars.
Where is RS Ophiuchus?
eastern Ophiuchus
RS Ophiuchi is located in eastern Ophiuchus near the Serpens border and well-placed for observing at nightfall. Since then, the star has brightened up to magnitude 4.5 (August 9.7 UT), making it a relatively easy naked-eye object even from outer suburban areas and a cinch to see in binoculars.
Who discovered Ophiuchi?
1985: In January of 1985, Warren Morrison (MOW) of Peterborough, Canada discovered RS Oph to again be in outburst (see IAUC 4030).
How many recurrent novae are there?
As of 2009, there are ten known galactic recurrent novae, as well as several extragalactic ones (in the Andromeda Galaxy (M31) and the Large Magellanic Cloud).
Are Novas rare?
Are Novas rare? The 1978 Chevy Nova 9C1 Coupe may be the rarest Nova ever produced. Almost all other Police Novas were built as four-doors. Research has turned up only a single example built as a coupe ordered as a 9C1 (there may be others, but documented examples have not been located).
Will there be a supernova in 2022?
In 2022—only a few years from now—an odd type of exploding star called a red nova will appear in our skies in 2022. This will be the first naked eye nova in decades. And the mechanism behind it is fascinating as well.
What is the story behind Ophiuchus?
In ancient Greece, Ophiuchus represented Asclepius, the god of medicine and the son of the god Apollo. In one version of this story, Asclepius killed a snake with his staff. But another snake dropped some herbs on the dead one, bringing it back to life.
Is Ophiuchi still visible?
RS Ophiuchi (RS Oph) is a recurrent nova system approximately 5,000 light-years away in the constellation Ophiuchus. In its quiet phase it has an apparent magnitude of about 12.5. It has been observed to erupt in 1898, 1933, 1958, 1967, 1985, 2006 and 2021 and reached about magnitude 5 on average.
Can supernovas repeat?
IT JUST keeps on banging. A dying star was caught mid-explosion in September 2014 and still isn’t done. It has lasted 10 times longer than any other supernova of its type that we’ve seen.
How do you say Ophiuchus?
According to the International Phonetic Alphabet (IPA), one pronounces Ophiuchus /ɒfiˈjuːkəs/. In plain old English, people pronounce Ophiuchus as “oh-FEW-kuss.”

What are hyper Novas?
A hypernova (alternatively called a collapsar) is a very energetic supernova thought to result from an extreme core-collapse scenario. In this case a massive star (>30 solar masses) collapses to form a rotating black hole emitting twin energetic jets and surrounded by an accretion disk.
Is a nova a dying star?
A supernova is a massive explosion of a dying star. The event occurs during the last evolutionary stages of a massive star, which is dying. The explosions are extremely bright and powerful.
How do Novas occur?
A nova is an explosion from the surface of a white-dwarf star in a binary star system. A nova occurs when the white dwarf, which is the dense core of a once-normal star, “steals” gas from its nearby companion star. When enough gas builts up on the surface of the white dwarf it triggers an explosion.
Is a 4 door nova rare?
To the best of my knowledge, this is one of the most rare Novas ever made. There were only seven four speed, four door Nova Concours made in 1977. As far as I know, there is only one like this.
How nova got the star in her eye?

Will the sun explode?
While the full death of the Sun is still trillions of years away, some scientists believe the current phase of the Sun’s life cycle will end as soon as 5 billion years from now. At that point, the massive star at the center of our Solar System will have eaten through most of its hydrogen core.
Will a supernova destroy Earth?
A supernova is a spectacular explosion of a massive star. If our sun exploded as a supernova, the resulting shock wave probably wouldn’t incinerate the entire Earth, but the side of Earth facing the sun would boil away.
Will I see a supernova in my lifetime?
Unfortunately, supernovae visible to the naked eye are rare. One occurs in our galaxy every few hundred years, so there is no guarantee you will ever see one in our galaxy in your lifetime.
