This is where the concept of the "observable universe" — the universe that we can see — comes into play. In 1 trillion to 2 trillion years, Livio said, this means that there will be galaxies that are beyond what we can see from Earth. "We can only see light from galaxies whose li...
We can estimate the age of the universe based on the rate of expansion. Because some galaxies are billions of light years away from us, we can discern that they formed fairly soon after the big bang (as you look deeper into space, you see further back in time). Most galaxies formed ...

\ The Earth and Distance to the Sun. Radar reflections from Venus and its angular separation from the Sun are used to calculate the numerical value of the Astronomical Unit (AU). You can use radar to measure distances out to 50 AU. Rung 2: Geometric Methods On the next rung of the ...
not much is known about them scientists think these galaxies are two of the brightest galaxies in our universe. You can’t exactly see these three galaxies properly. They look like small, hazy patches of light. We need to research more about these galaxies and see if we find intelligent ...
Whilst you can argue Imagine Earth doesn't necessarily do anything new, its use of its campaign to send out a message of sustainability with one's own environment sets it apart. It may not scratch the itch of hardcore Anno style players but if you're in the market for a relaxing world...
The Pinwheel galaxy can be located with your telescope by star-hopping from the bright star Alkaid, in the handle of theBig Dipper. Though it is bright enough to capture from your backyard, you’ll need to focus on getting plenty of exposure time (2-3 hours), a healthy signal-to-noise...
The KCRM can see further into the red, meaning it can see more redshifted light. While the KCWI spans a range from 350 nm to 560 nm, the KCRM can see from 530 nm to 1050 nm. The new instrument's range means our image of the cosmic web is about to improve. ...
