Betelgeuse is so close and so big that telescopes here on Earth are able to reveal the surface of the star as a disk, seeing individual features like huge convection cells. First, let's take a look at the star as it was seen back in January 2019 using SPHERE. You can see how the star looks like a bright sphere.14-Feb-2020
Can you see the disc of a star?
Astronomers have imaged disks around young stars like LkHa 101 and IRAS 13481–6124, and also binary systems like Wolf-Rayet 104, Epsilon Aurigae, and Beta Lyrae. Our typical “unit of measure” for these types of images is the milliarcsecond, or one one-thousandth of an arcsecond.
Can we see Betelgeuse explode?
Betelgeuse is a red supergiant — a type of star that's more massive and thousands of times shorter-lived than the Sun — and it is expected to end its life in a spectacular supernova explosion sometime in the next 100,000 years.
Can we see Betelgeuse from Earth?
You can see Betelgeuse with the naked eye. To find it, look first for the three stars that make up Orion's Belt. This famous star pattern ('asterism') will be rising above the eastern horizon at 3am at the start of September, getting earlier each night (by the end of September, it'll rise just after 1am).
Can you see Beetlejuice with the naked eye?
Betelgeuse is easily visible to the eye, and you won't see much more detail using binoculars or a telescope. The star is so intriguing that the Hubble Space Telescope periodically turns its powerful gaze on Betelgeuse to see what scientists can learn.
Are there any photos of exoplanets?
Of the thousands of exoplanets discovered so far orbiting distant stars, earthly astronomers have captured direct images of only a very few. In each of these images, only one planet can be seen. Now astronomers say they've acquired a first-ever direct image of two giant exoplanets, orbiting a sunlike star.
Do we have pictures of other stars?
Astronomers have produced the most detailed ever images of a star other than the sun. The red supergiant, called Antares, is known as the heart of the Scorpius constellation because of its rosy hue, discernible to the naked eye, and location in the body of the astronomical beast.
Will we see a supernova in 2022?
This is exciting space news and worth sharing with more sky watch enthusiasts. 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.

Is Betelgeuse visible without a telescope?
At near-infrared wavelengths, Betelgeuse is the brightest star in the night sky. Its Bayer designation is α Orionis, Latinised to Alpha Orionis and abbreviated Alpha Ori or α Ori. Classified as a red supergiant of spectral type M1-2, Betelgeuse is one of the largest stars visible to the naked eye.
