UNIVERSE TODAY

On February 13, 2019, NASA tweeted out a sad message: To the robot who turned 90 days into 15 years of exploration: You were, and are, the Opportunity of a lifetime. Rest well, rover. Your mission is complete. It’s strange to get choked up a little saying these words. To feel sad about a robot on another planet. But I’m guessing you feel the same way. And today I wanted to look back at the history of the Mars Exploration Rovers, Spirit and Opportunity. To take you through their creation, launch to Mars, the amazing discoveries they made, and of course, how they finally died.

Astronomers working with the NASA’s Chandra X-Ray Observatory and ESA’s XMM-Newton have developed a technique to watch quasars and track the expansion of the Universe over the last 9 billion years. What they found is that the mysterious dark energy that’s currently accelerating the expansion of the Universe doesn’t appear to be a fixed amount. It’s changing, and appears to be increasing over time. If true, it’s a groundbreaking discovery in cosmology, and it could just fortel the end of the Universe.

Geologists think they’ve found the oldest Earth rock ever seen. And they found it in one of the last places you’d ever suspect, on the Moon. When the Apollo 14 astronauts returned their lunar samples back to Earth, they were carrying one rock that had formed on Earth 4 to 4.1 billion years ago, which was carved out of our planet during the time of intense bombardment and delivered to the Moon.

As astronomers find more and more planets around other stars, the big question we want to know is: are they habitable, could there be life there? The vast majority of stars in the Milky Way are red dwarf stars, and most of the planets in habitable zones have been found orbiting these cooler, less massive stars. What are the chances that life could get going on these worlds?

One of the big mysteries in astronomy is unfolding right before our eyes: fast radio bursts. And now a new Canadian radio telescope has come online, detecting many new bursts, including the second ever seen repeating. Finally, with the right tools at their disposal, astronomers are going to be able to get to bottom of this puzzling mystery.

Are we alone in the Universe? It’s one of the most difficult and important questions that humanity can ask. As Arthur C. Clarke noted, it’s equally terrifying whether the answer is yes or no. So if you’re going to find evidence of extraterrestrial civilizations, you want to be absolutely certain about your evidence. You want to find “technosignatures”, unmistakable proof that aliens are out there.

In this week's Open Space Live QA, I sat down with my friend John Michael Godier to talk about the projects he's working on. We had a wide ranging discussion about the latest research in exoplanets, interstellar asteroids, the search for Planet 9, and other places in the Solar System that we really should be exploring.

The distances between stars are so vast, it’s hard to wrap your mind around it. Even our far flung Voyagers have barely reached interstellar space, and would take tens of thousands of years to get to even the nearest star. But scientists and engineers are considering what it would actually take to send a spacecraft to another star. It’s called Project Dragonfly, and would use existing or near future technologies to send a 3,000 kg spacecraft to Alpha Centauri within 100 years.

Thanks to the hardworking Gaia spacecraft, astronomers think they’ve located a star that formed from the same solar nebula as the Sun. In fact, this star is a virtual twin of the Sun and it’s actually pretty close. Well, astronomical speaking.

It’s been about a year since the mysterious interstellar asteroid (or maybe comet) Oumuamua passed through our Solar System. It was going so fast and was so far away that astronomers could see very little before it was off and away into deep space again. The strange motions of the object as it zipped through the Solar System have left astronomers puzzled about what it is, and some interesting theories are continuing to come out to explain it. And one really extreme idea is that it could be a solar sail sent from another civilization.

In the pristine icy environment of Antarctica, there’s a telescope, embedded into an ancient glacier. The telescope is observing the Universe, directly through the Earth, using a cubic kilometer of ice to capture elusive particles called neutrinos. These ghostlike particles are streaming from the Sun, coming from exploding stars millions of light-years away, gamma ray bursts, colliding neutron stars and black holes. And maybe, just maybe, it’s going to be the instrument that finds dark matter.

The Earth’s atmosphere keeps us safe from the harsh environment of space, but it also obscures our view into the cosmos. No matter how powerful a telescope you build, the turbulence of the atmosphere limits your resolution. But astronomers and engineers have an amazing technology that allows a telescope to peer into space as if the atmosphere isn’t even there, producing images from here on the ground which are as sharp and clear as if the telescope was out in space. It’s called adaptive optics, and we’re now at the point where the most powerful ground-based telescopes have matched and even exceeded the capability of space telescopes.

Professor Avi Loeb is one of the hardest working astrophysicists in the field, writing a blistering number of academic papers on fascinating topics like the Fermi Paradox, the habitability of other worlds, black holes, and the history of the early universe.

This week I'm joined by sci-fi author and futurist David Brin. He's best known for the Uplift Stories, and other sci-fi novels, but he's been active in space science, sitting on the board of NASA's Innovative and Advanced Concepts awards. Here's the link that David mentioned about lifting the Earth. https://www.youtube.com/watch?v=Ai8x-ZqjXPc

My live guest this week will be Professor Brad Peterson, from Ohio State University. In addition to his professoring duties, Dr. Peterson is the Community Chair of the Science and Technology Definition Team for the Large Ultraviolet Optical and Infrared Surveyor (LUVOIR). We'll talk all about the plans for this massive space telescope, the true successor to the Hubble Space Telescope.

Join me and Cory Schmitz from Photographing Space for a livestream of Friday's total lunar eclipse. Cory is perfectly positioned in South Africa for a great view of the Moon throughout the entire lunar eclipse. We'll also be joined by other special guests to talk all things space and astronomy, to enjoy this spectacle together.

In this week's QA, I explain why dark matter is really a thing, and not just some made up thing by evil astronomers. How event horizons flatten out when they spin, what kind of scientist I'd want to be, and if you could build a ladder to space.

Join me for a live hour of QA.

Astronomers have finally solved one of the outstanding mysteries in cosmology. Forget about all the dark matter and dark energy, where’s all the missing regular mass in the Universe? This has been called the “missing baryon problem”. They’ve been chipping away at the problem, finding missing matter in the vast gulfs between galaxies, and in the last few months, a team of astronomers have finally found the outstanding missing matter.

Until we learned to properly navigate our way across the oceans, early explorers were fearful to lose sight of land in case they’d be lost at sea. They learned to use the water currents, winds, movements of birds and of course, the positions of the Sun, the Moon and the stars to find their way across the seas to distant lands. As we learned to launch spacecraft into orbit and out into the Solar System, mission planners needed to develop entirely new methods of navigation.
