What did NASA see on august 20 2016?

APOD: 2016 August 20 – Gamma rays and Comet Dust.

When did NASA picture of the day start?

What is Nasa’s picture of the day? The Astronomy Picture of the Day (APOD) is a website provided by Nasa and Michigan Technological University. The initiative has been running since 1995 with all the images stored in the APOD Archive.

How did NASA take a picture of the galaxy?

Nasa’s new space telescope has gazed into the distant universe and shown perfect vision: a spiky image of a faraway star photobombed by thousands of ancient galaxies.

What did NASA saw on January 6 2020?

Astronomy Picture of the Day The featured tumultuous clouds were captured in May by NASA’s robotic Juno spacecraft currently orbiting our Solar System’s largest planet. The image was taken when Juno was only about 15,000 kilometers over Jupiter’s cloud tops, so close that less than half of the giant planet is visible.

What did NASA saw on July 13 2007?

The astronomers observed the eclipse with Spitzer’s infrared array camera at three different infrared wavelengths and noticed that for each wavelength a different amount of light was absorbed by the planet.

Are galaxy photos real?

TLDR: Yes, Hubble images are real. This series of posts is dedicated to the scrutiny of Hubble imagery and a broader discussion of the veracity of astronomical imagery. In this post, we’ll take a brief look at the history of astrophotography in order to provide a historical context to Hubble.

How do I find my birthday photos of NASA?

Finding the picture NASA took on your birthday is actually surprisingly simple. All you need to do is head to NASA’s website and key in your birthday. Then, you’ll see an image of the universe on that exact date and some details about the image.

What are cosmic rays?

Cosmic rays provide one of our few direct samples of matter from outside the solar system. They are high energy particles that move through space at nearly the speed of light.

Do cosmic rays come from supernova remnants?

However, cosmic rays have been observed at much higher energies than supernova remnants can generate, and where these ultra-high-energies come from is an open big question in astronomy. Perhaps they come from outside the galaxy, from active galactic nuclei, quasars or gamma ray bursts.

What is the average age of cosmic rays?

With this method, the average age of cosmic rays comes out to approximately ten million years. The reason the two million year age from the previous paragraph is wrong is that cosmic rays don’t just stay in the regions where the density is one atom per cubic centimeter (such as the galactic disk ).

Why can’t we trace the path of cosmic rays?

Because cosmic rays carry electric charge, their direction changes as they travel through magnetic fields. By the time the particles reach us, their paths are completely scrambled, as shown by the blue path. We can’t trace them back to their sources. Light travels to us straight from their sources, as shown by the purple path.
