How far away is dark matter from Earth?Dark Matter:Dark matter is matter that does not interact with light, making it impossible for researchers to see it. Fortunately, dark matter has mass and interacts with gravity, allowing a way to indirectly observe it....
The article discusses how identifying the various regions within the Orion Nebula (M42) could help astronomers understand how stars and planets form. Topics include how stars are formed within the Orion Nebula, a three-dimensional (3D) diagram showing a region within M42 near the Trapezium star ...
In this post, I’ll break down how to photograph theOrion Nebula, one of the most spectacular deep-sky objects in the night sky. While it may just look like a smudge to the naked eye, Orion is the nearest, large star-forming region to Earth at just 1,500 light years away. When yo...
Orion Nebula and smart telescopes If you own a smart telescope, you may be wondering how this applies to you. Smart scopes work by taking short exposures and live-stacking them. If you’re relying on the output of your device, the key is to limit the number of live-stacked exposures, ...
To understand how telescopes work, let's ask the following question. Why can't you see an object that is far away? For example, why can't you read the writing on a dime when it is 150 feet away with your naked eyes? The answer to this question is simple: the object does not...
The reflector telescope, which uses mirrors instead of the lenses. Both types accomplish exactly the same thing, but in completely different ways. To understand how telescopes work, let's ask the following question. Why can't you see an object that is far away? For example, why can't...
How close is the Hubble Telescope to the moon? How far can the James Webb Space Telescope see? Can the Hubble Space Telescope measure speed or distance? How long is the Hubble Space Telescope's orbital period? What does the Hubble Telescope do in space? How far is Aldebaran from Earth?
“The camera on the 8.4-meter telescope of the upcoming Vera Rubin Observatory has 3.2 billion pixels!” That’s the largest digital camera ever built. Related Stories The Best Telescopes Every Image From the Webb Space Telescope (So Far) Among the dozens of superpowerful telescopes across the...
Well... so far, so good > Telescopes are like camera lensesin that you appropriately choose short small scopes for big expansive subjects and long big scopes to bring in the remote little subjects. The Orion Nebula (and a couple dozen favorite others) is huge and close --- so favors cut...
So, when photographing deep space, how come the light from adjaicent and nearby stars not blur the picture and ruin it? I'm a huge newbie but as far as I understand it...the camera has to be in sync with Earth's rotation, or the stars WILL blur. I take pictures with a Dwarf ca...
