Space and astronomy news
Have you ever seen the videos of people taking daily selfies of themselves over the course of years or even decades? Now the sun has started it’s own series of pictures – with 366 complete pictures from the year 2020, captured by the European Space Agency’s Proba-2 satellite.

Navigating and mapping rivers has long been a central component in human exploration. Whether it was Powell exploring the Colorado’s canyons or Pizarro using the Amazon to try to find El Dorado, rivers, and our exploration of them, have been extremely important. Now, scientists have mapped out an entirely new, unique river basin. This one happens to be on an entirely different planet, and dried up billions of years ago.

The field of exoplanet photography is just getting underway, with astronomers around the world striving to capture clear images of the more than 4000 exoplanets discovered to date. Some of these exoplanets are more interesting to image and research than others. That is certainly the case for a type of exoplanet called a brown dwarf. And now scientists have captured the first ever image of exactly that type of exoplanet.

Other worlds aren’t the only difficult terrain personnel will have to traverse in humanity’s exploration of the solar system. There are some parts of our own planet that are inhospitable and hard to travel over. Inner Mongolia, a northern province of China, would certainly classify as one of those areas, especially in winter. But that’s exactly the terrain team members from the China Aerospace Science and Technology Corporation (CASTC) had to traverse on December 16th to retrieve lunar samples from the Chang’e-5 mission. What was even more unique is that they did it with the help of exoskeletons.

A very rare astronomical phenomenon has been in the headlines a lot recently, and for good reason. It will be hundreds of years until we can see Jupiter and Saturn this close to one another again. However, there are some even more “truly strange and very rare phenomena” that can currently be observed in our night sky. The only problem is that in order to observe this phenomena, you’ll need access to Hubble.

Minute vibrating strings found in string theory are not the only ones that are of interest to physicists. The Standard Model of particle physics provides for a theory regarding a different type of string – this one is a string of very sparse gas strung over very long distances. In fact, the standard model predicts that a large percentage of “baryonic matter” (i.e. the type that makes up everything we can see and interact with) would be contained in these filaments. And now for the first time, scientists led by a team at the University of Bonn in Germany have detected one of these super long strings of gas.

Sometimes in astronomy the acronym for a project fits it particularly well. That would absolutely be the case for the Giant Radio Array for Neutrino Detection, who hopes to scale up to a size of 200,000 sq km in an effort to measure ultra-high-energy tau-neutrinos. Is it ambitious? Yes, but that doesn’t really stop humanity from exploring when it wants to.

Funding is an extremely important aspect of any large-scale science project. The whims of financial controllers can greatly expand or completely sink the efforts of hundred or thousands of other workers. Many times, funding announcements for large scientific projects focus on cuts or “cost-savings” which hobble the eventual end system they are trying to build. But recently the European Southern Observatory (ESO) announced it had actually increased the budget for the under-construction Extremely Large Telescope (ELT) by 10%.

One of the best things about astronomy is that it’s a never-ending supply of awesome visuals. Almost every new mission or telescope provides new ways to see the universe, and when those are translated visually they can offer absolutely stunning images of some of the most interesting places in that universe. Now humanity is starting to process the images from one of the newer missions to grace the heavens: the European Space Agency’s Solar Orbiter. And boy are those images breathtaking.

Lately there has been a flood of interest in gravitational waves. After the first official detection at LIGO / Virgo in 2015, data has been coming in showing how common these once theoretical phenomena actually are. Usually they are caused by unimaginably violent events, such as a merging pair of black holes. Such events also have a tendency to emit another type of phenomena – light. So far it has been difficult to observe any optical associated with these gravitational-wave emitting events. But a team of researchers hope to change that with the full implementation of the Gravitation-wave Optical Transient Observer (GOTO) telescope.
