When you think about what’s out there in the abyss of deep space, whether you’re looking out at the planets in our Solar System or the most distant galaxies perceptible in the Universe, the instrument most people think about using for the best images and data is the Hubble Space Telescope. Perched hundreds of miles above the Earth’s atmosphere, issues like clouds, atmospheric distortion, turbulent air, or even pollution are no concern. Images are as sharp as the cameras and optics on board allow, and from its position off-world, it can look in any direction we want it to. Using it, we’ve seen wonders the likes of which we’ve never imagined; Hubble has shown us what the Universe truly looks like.

And yet, there are things we can do from the ground that are indisputably superior to anything we can do from space. There are images we can create and data we can collect that are simply impossible to do from space. Whether we’re using ground-based telescopes, balloon-borne observatories or even a high-altitude aircraft, there are many good reasons to remain here on Earth. Sure, flying above the atmosphere and receiving the omnidirectional perspective that going to space gives you are definite victories for the space telescope aficionados; there’s no way adaptive optics or a pristine observing site can compete with an observatory that doesn’t have the Earth to contend with. But there are some very compelling reasons to do astronomy on the ground, as there are benefits that you lose the instant you go to space. Here are the top five:

Via a radio telescope in Western Australia!
Surprises in signal from cosmic dawn also hint at presence of dark matter.
Astronomers have for the first time spotted long-sought signals of light from the earliest stars ever to form in the Universe — around 180 million years after the Big Bang.
The signal is a fingerprint left on background radiation by hydrogen that absorbed some of this primordial light. The evidence hints that the gas that made up the early Universe was colder than predicted. This, physicists say, is a possible sign of dark matter’s influence. If confirmed, the discovery could mark the first time that dark matter has been detected through anything other than its gravitational effects.

So what caused the formation of the Solar System? One possibility is the shock from a low mass Supernova explosion.
A research team led by University of Minnesota School of Physics and Astronomy Professor Yong-Zhong Qian uses new models and evidence from meteorites to show that a low-mass supernova triggered the formation of our solar system. The findings are published in the most recent issue of Nature Communications, a leading scientific journal.

Further evidence about the Earth being struck by a large, Mercury size object in the early life of the Solar System
Research by Rice University Earth scientists suggests that virtually all of Earth’s life-giving carbon could have come from a collision about 4.4 billion years ago between Earth and an embryonic planet similar to Mercury.
In a new study this week in Nature Geoscience, Rice petrologist Rajdeep Dasgupta and colleagues offer a new answer to a long-debated geological question: How did carbon-based life develop on Earth, given that most of the planet’s carbon should have either boiled away in the planet’s earliest days or become locked in Earth’s core?

The MAVEN mission has identified the process that appears to have played a key role in the transition of the Martian climate from an early, warm and wet environment that might have supported surface life to the cold, arid planet Mars is today.

More irregular dimming. Another Tabbi’s Star?
New research conducted by a team of astronomers, led by Simone Scaringi of the Max Planck Institute for Extraterrestrial Physics in Germany, examines peculiar dimming of a newly found young stellar object designated EPIC 204278916. The study tries to explain the nature of these dipping events observed in the object’s light curve. The results were published Aug. 25 in a paper available on arXiv.org.

Gemini Planet Imager (GPI) was designed, built, and optimized for imaging faint planets next to bright stars and probing their atmospheres. It will also be a powerful tool for studying dusty, planet-forming disks around young stars. It is the most advanced such instrument to be deployed on the 8-meter Gemini South telescope in Chile.

Striking new observations with the Atacama Large Millimeter/submillimeter Array (ALMA) telescope capture, for the first time, the remains of a recent supernova brimming with freshly formed dust. If enough of this dust makes the perilous transition into interstellar space, it could explain how many galaxies acquired their dusty, dusky appearance.
