Can you shine a flashlight in space?
Essentially yes. Some of the photons will go all the way to the edge of the universe, taking many billions of years to get there. People seem to think that because a flashlight is not very bright all of it must get absorbed before it leaves the atmosphere.
What happens if you light a flashlight in space?
Any wavelength of light will. This becomes a problem for space probes, because electronics and power supplies turning on and off create heat in the infrared spectrum, and these infrared photons cause a small thrust which over long periods of time will cause the probe to veer off course.
Do astronauts use flashlights?
Sure. They use flashlights all the time in space during EVAs. Here is a pic of an astronaut wearing a spacesuit and helmet in the ISS with his two headlamps on both sides of the helmet turned on.
Can a flashlight reach the moon?
Yes. If there is nothing opaque in the way to obstruct it, it will reach the moon. However, the intensity of light (from a point source like a torch) diminishes with the square of distance. So, by the time it reaches the moon, it will be extremely faint.
How far can a flashlight be seen in space?
Re: How far can a flashlight be seen? 50 miles in clear atmosphere for a sufficiently bright and/or focused light.
Can you see a spotlight from space?
We’ve seen lots of images and videos of city lights on Earth as seen from the International Space Station. But if you were down on Earth, flashing a light at the astronauts on the ISS – would they see you? The answer is now definitively, yes.

What’s the brightest city on earth?
The major Denver street patterns are rectilinear, aligned north-south and east-west. The “Vegas Strip” of casinos and hotels—reputed to be the brightest spot on Earth—stands out in the center of this image due to both its brightness and its diversity of light colors.
Can astronauts see people from space?
I’ve often been asked the question, “Can the astronauts on the Space Station see the stars?” Astronaut Jack Fischer provides an unequivocal answer of “yes!” with a recent post on Twitter of a timelapse he took from the ISS. Just like stargazers on Earth need dark skies to see stars, so too when you’re in space.
How much money does an astronaut make per hour?
