Is a star a period variable star?

The radius of the star would extend outward to at least the orbit of Jupiter and is a long period variable star.

Why is the nebula black?

The reason why the patch appears black has not yet been determined, but one theory suggests that narrow jets of gas from the neighbouring young stars may have punctured the sheet of dust and gas in the nebula and strong radiation from an older star in the region may have helped create the hole.

What do we know about Betelgeuse?

The supergiant star’s formal moniker is derived from a mistranslated Arabic name meaning “the hand of Orion” ( yad al-jauza ). Today, many people pronounce the name like the titular character in Tim Burton’s 1988 film Beetlejuice. The star is also referred to as Alpha Orionis, a designation normally reserved for the brightest star in a constellation, even though Rigel, at Orion’s left foot, is actually brighter.

How long do we have to wait for the fireworks?

Recent studies suggest that the star will most likely explode within the next million years, and perhaps as soon as 100,000 years from now. Or … maybe Betelgeuse has already exploded and we have not yet seen it happen.

Why do supergiant stars darken?

The reasons for these quasiperiodic changes in variations are somewhat unclear. Guinan and others say that supergiant stars like Betelgeuse have mottled surfaces containing massive convective cells that shrink and swell, which cause such stars to darken and brighten, but that’s not the whole story.

Why is Betelgeuse dimmer?

Guinan suspects that Betelgeuse is dramatically dimmer now because two of its cycles are overlapping at minimal brightness. In essence, the star is approaching the dimmest points in both its six-year and 425-day cycles, an intersection that makes the star’s normal fluctuations appear much more sinister.

What is the red giant star?

A giant star is acting strange, and astronomers are buzzing. The red giant Betelgeuse is the dimmest seen in years, prompting some speculation that the star is about to explode. Here’s what we know. The constellation Orion is one of the most recognizable patterns in the night sky, visible around the world. But if you’ve looked at Orion recently and …

What star is the hunter in the constellation Orion?

A meteor streaks past the constellation Orion, the hunter, as it hovers over the horizon. The bright, ruddy star Betelgeuse (left) is part of this famous stellar pattern.

What is the most recognizable constellation in the night sky?

The constellation Orion is one of the most recognizable patterns in the night sky, visible around the world. But if you’ve looked at Orion recently and thought something seemed off, you’re not wrong: The giant red star Betelgeuse, which marks the hunter’s right shoulder, is the dimmest it’s been in almost a century.

What is the red dot on Orion’s shoulder?

A bright red dot called Betelgeuse marks Orion’s shoulder, and this star’s strange dimming has captivated skygazers for thousands of years. Aboriginal Australians may have even worked it into their oral histories. Today, astronomers know that Betelgeuse varies in brightness because it’s a dying, red supergiant star with a diameter some 700 times …

What constellation is on the shoulder of the Hunter?

If you stargaze on a clear winter night, it’s hard to miss the constellation Orion the Hunter, with his shield in one arm and the other arm stretched high to the heavens. A bright red dot called Betelgeuse marks Orion’s shoulder, and this star’s strange dimming has captivated skygazers for thousands of years. Aboriginal Australians may have even worked it into their oral histories.

What program did Astronomers use to simulate what humans might see when the star Betelgeuse explodes?

Astronomers used a software program called MESA+STELLA to simulate what humans might see when the star Betelgeuse explodes. They also included observations gathered during Supernova 1987A, which exploded in the Large Magellanic Cloud. Jared Goldberg/University of California, Santa Barbara/MESA+STELLA.

Why do red supergiant stars grow?

As their nuclear fuel runs out near the ends of their lives, red supergiant stars start to bloat and form growing envelopes of gas and dust. And as this envelope gets bigger, the star’s brightness grows. But that’s not the only way a star like Betelgeuse can dim and brighten.

How long can we see supernovae?

Humans would be able to see the supernova in the daytime sky for roughly a year, he says. And it would be visible at night with the naked eye for several years, as the supernova aftermath dims. “By the time it fades completely, Orion will be missing its left shoulder,” adds Sarafina Nance, a University of California, Berkeley, …

How far away is Betelgeuse?

Betelgeuse is far outside that range, with recent studies suggesting it sits roughly 724 light-years away, well outside the danger zone. But the supernova could still impact Earth in some surprising ways. For example, Howell points out that many animals use the Moon for navigation and are confused by artificial lights.

When did Betelgeuse start dimming?

That eventual explosion explains why astronomers got excited when Betelgeuse started dimming dramatically in 2019. The 11th-brightest star dropped in magnitude two-and-a-half-fold. Could Betelgeuse have reached the end of its life? While unlikely, the idea of a supernova appearing in Earth’s skies caught the public’s attention.

What wavelength is the Betelgeuse star?

This composite photo of the red supergiant star Betelgeuse combines images captured by the Herschel Space Telescope in wavelengths of 70, 100 and 160 microns. (Image credit: ESA/Herschel/PACS/L. Decin et al)

How many times does the diameter of the Sun change?

Professional astronomers also keep a close eye on the star, as it is notoriously variable: its diameter changes from anywhere between 550 to 920 times the sun’s diameter. In 2013, astronomers said Betelgeuse is likely to crash into a "cosmic wall" of interstellar dust in a few thousand years.

Why is Betelgeuse a red giant?

Betelgeuse is a star nearing the end of its life. Because it is creating heavier and heavier elements in its core that could be used for stars after it dies, a NASA story once dubbed the red giant a workaholic.

How far away is Betelgeuse?

Ancient astronomers would have easily spotted Betelgeuse because of its size and relatively close distance from Earth: it is about 600 light-years away and has a variable brightness generally peaking at 0.4 and falling below 1.2. Some 20th-century observations by the American Association of Variable Star Observers suggested peak magnitudes of 0.2 in 1933 and 1942. It is the 12th brightest star in the night sky. [ The Brightest Stars in the Sky: A Starry Countdown]

What telescope took the first image of Betelgeuse?

In 2017, the Atacama Large Millimeter/submillimeter Array Telescope (ALMA) took its first image of Betelgeuse’s surface, which astronomers said was the highest-resolution image yet obtained of the star.

When will Betelgeuse explode?

When astronomers say Betelgeuse is expected to explode soon, they mean shortly in astronomical terms: within a million years, according to several sources. Predicting exactly when it will turn into a supernova is difficult, however, as it depends on precise calculations of its mass as well as an understanding of what is going on inside the star.

How fast is Betelgeuse’s rotation?

Meanwhile, scientists remain puzzled by Betelgeuse’s ultra-fast rotation, which is about 150 times faster than expected. This may have happened if the star swallowed a sun-mass star about 100,000 years ago, according to a 2016 study.
