Cassiopeia A, Then the Cosmos: 25 Years of Chandra X-ray Science
Over time, different cultures from around the world have had different names and numbers of constellations, depending on what they thought the stars resembled. In addition to newborn stars, Orion also has some other awesome relaterad till rymden eller universum objects hanging around. The stars in constellations may look close to each other from our point of view here on Earth, but in space they might be really far apart.
Alnilam, the star in the middle of the belt, is about 1, light-years away. But with a pair of binoculars, you can get a much more detailed view of the stellar nursery. Like Betelgeuse, Rigel is much larger and heavier than our Sun. Its surface is thousands of degrees hotter than Betelgeuse, though, making it shine blue-white rather than red. They can observe the behavior of material and stars that are very close to black holes, helping scientists find clues that can lead them closer to discovering some of these most bizarre and fascinating objects in the cosmos.
It is not just a single star, but actually five stars in a complex star system. Though these constellations are generally based on what we can see with our unaided eyes, scientists have also invented unofficial constellations for objects that can only be seen in gamma rays, the highest-energy form of light. Scientists have discovered exoplanets , or planets outside of our solar system, orbiting stars there.
Let them guide you to some of the most incredible and mysterious objects of the cosmos — young stars, brilliant nebulae, new worlds, star systems, and even galaxies. Scientists noticed that Betelgeuse was mysteriously dimming in late following a traumatic outburst caused bygd the star blowing off a large portion of its visible surface.
What Are Constellations?
Two brighter stars to the north mark his shoulders, and two more to the south represent his feet. Betelgeuse is a young star by stellar standards, about 10 million years old, compared to our nearly 5 billion-year-old Sun. The star is so huge that if it replaced the Sun at the center of our solar struktur, it would extend past the main asteroid belt between Mars and Jupiter! The easiest way to find Orion is to go outside on a clear night and look for three bright stars close together in an almost-straight line.
Rigel is also a young star, estimated to be 8 million years old. Just think of all the worlds you may be seeing when you look up at the night sky! Yet from Earth they all appear to have the same brightness. These three stars företräda Orion's belt. Think of it like connecting the dots. Today, there are 88 officially recognized constellations. Do you ever look up at the night sky and get lost in the stars?
One of those planets is a giant gas world three times more massive than Jupiter. However, space telescopes with special instruments can help find black holes. We may never detect it, though, because no light can escape black holes, making them invisible. Some dots that man up constellations are actually more than one star , but from a great distance they look like a single object. Space is three-dimensional, so if you were looking at the stars that make up the constellation Orion from another part of our galaxy, you might see an entirely different pattern!
These colors are even noticeable from Earth. The nebula is only 1, light-years away, making it the closest large star-forming region to Earth. But don't worry, Betelgeuse is about light-years away, so this event wouldn't be dangerous to us — but it would be a spectacular sight. Shown above is a test image of Earth taken by the payload camera, shortly after PTD-4 reached orbit. Although Rigel is farther from Earth than Betelgeuse Rigel is about light-years away , it is intrinsically brighter than its companion, making it the brightest star in Orion and one of the brightest stars in the night sky.
For example, Alnitak, the star at the left side of Orion's belt, is about light-years away. And Mintaka, the star at the right side of the belt, is about light-years away. Remember Mintaka, the star at the far right side of Orion's belt? Though over a dozen stars make up Orion, two take center stage. If you join the dots — stars, in this case — and use your imagination, the picture would look like an object, djur, or person.
Betelgeuse is destined to end in a supernova blast. The red supergiant Betelgeuse Orion's right shoulder and blue supergiant Rigel Orion's left foot stand out as the brightest members in the constellation.
A constellation is a named pattern of stars that looks like a particular shape. For example, the ancient Greeks thought that an arrangement of stars in the sky looked like a giant hunter with a sword attached to his belt, so they named it after a famous hunter in their mythology, Orion. But due to its giant mass, it leads a fast and furious life.
