If you thought dark matter was difficult to study, studying dark energy is even more challenging. Dark energy is perhaps the most subtle phenomenon in the universe. It drives the evolution of the cosmos, but its effects are only seen on intergalactic scales. So to study dark energy in detail, you need a great deal of observations of wide areas of the sky.

Alien Artifacts Could Be Hidden Across the Solar System. Here’s how we Could Search for Them.
Do aliens exist? Almost certainly. The universe is vast and ancient, and our corner of it is not particularly special. If life emerged here, it probably did elsewhere. Keep in mind this is a super broad assumption. A single instance of fossilized archaebacteria-like organisms five superclusters away would be all it takes to say, “Yes, there are aliens!” …if we could find them somehow.
Galactic Photobombing
This image, taken by the Hubble Space Telescope, appears to show two spiral galaxies colliding. In fact, they are just overlapping from our vantage point and are likely quite distant from each other. The galaxies are named SDSS J115331 and LEDA 2073461, and they lie more than a billion light-years from Earth. This ‘photobombing’ of one galaxy getting in the same picture as another was originally found by volunteers from the Galaxy Zoo project, which uses the power of crowdsourcing to find unusual galaxies in our Universe.
