NASA To Launch Telescope Stronger Than Hubble That Can See Back In Time

Everything we see is back in time.

Devs on Hulu.

[John Milner]

Have it see if it can tell where I left my cell phone yesterday.

[Seruzawa]

The European Space Agency is launching this.

So much for our worthless NASA.

[GingisK]

Maybe they can identify those responsible for the JFK assassination.

The higher resolution would allow us to observe additional objects and events not just further back in time but even very recent smaller objects or events that were previously undetectable.

Interesting the science of putting a distance on objects and events.

Can’t wait for the pics.

Did you have the bartender put in on a charger for you and forget it when you left?

If not, check the couch.

Call it from the house and listen for it the house and/or the car.

They’re probably launching this rocket from French Guiana because the launch pad is close to the equator. Maybe the telescope is going to a geosynchronous orbit.

Last night I read an article about some folks who were all upset about the telescope, because the NASA director it is named after was allegedly a homophobe. Myself, I’m just glad it isn’t named after the other James Webb, the former Virginia senator who wrote pornography on the side.

I wonder if it can clearly see Uranus?

The light we see from Sun is about 8 1/2 minutes back into the past.

Wow man. The solar system could have been destroyed already and we haven’t seen it yet. Far out. Isn’t marijuana legalization combined with public education so entertaining.

[epluribus_2]

186,000 miles per second.

It’s not just a good idea - it’s THE LAW.

[PfromHoGro]

No, it will be stationed very far away. I don’t think it’s a Legrange(?) point, but there will be no servicing opportunities. It has to work out of the box. Now its launch window starts at 7:20am Eastern Christmas morning, last I heard.

Actually, the speed of light is decided upon by international convention, not actual experimental proof.

Seems it varies dependent on how fast a clock one has....

Interesting read if one cares to “ science” it.

Generally, the SOL is figured by a clock and two mirrors, and the “time” lapse between images is averaged....but we all know that makes some unproven assumptions. Anyways, “seeing “ into deep space is not exactly the same as seeing “ back in time”. After all, the light producing the deep space image is making an image “ now” regardless of “when” that light was radiated.

Everything we see is back in time.

Right. Light waves take some time to travel from their source to our eyes. Even if an event occurs a few feet away, we are seeing the past.

Close to L2

I like when people show me a picture of themselves, and remark, "This was taken when I was younger."

I'm like, "DUH!"

The launch is currently scheduled for December 25th, 7:20am EST.

From https://www.nasa.gov/topics/universe/features/webb-l2.html

The Webb won't be orbiting the Earth –instead we will send it almost a million miles out into space to a place called "L2."

L2 is short-hand for the second Lagrange Point, a wonderful accident of gravity and orbital mechanics, and the perfect place to park the Webb telescope in space. There are five so-called "Lagrange Points" - areas where gravity from the sun and Earth balance the orbital motion of a satellite. Putting a spacecraft at any of these points allows it to stay in a fixed position relative to the Earth and sun with a minimal amount of energy needed for course correction.
