On Nov. 26th, 2018, NASA’s Interior Exploration using Seismic Investigations, Geodesy, and Heat Transport (InSight) lander arrived on Mars. Since then, this robotic mission has been using its advanced suite of instruments to study Mars’ interior and geological activity to learn more about its formation and evolution. One of these is the Seismic Experiment for Interior Structure (SEIS), the lander’s primary instrument, which was deployed on the Martian surface less than a month after it arrived.

What is the multiverse? The idea that the universe we inhabit is just one of many parallel universes gets a superhero shout-out in “Doctor Strange in the Multiverse of Madness,” the latest movie based on Marvel comic-book characters.

A team of researchers at the University of Tokyo have discovered a set of RNA molecules that are capable of replication and diversification. This potentially allows the molecules to undergo Darwinian evolution, pointing the way to a possible first step to life on Earth. As lead author Assistant Professor Ryo Mizuuchi said, “The results could be a clue to solving the ultimate question that human beings have been asking for thousands of years — what are the origins of life?”

One of the great things about science is that it builds on itself over time.  Data collected decades ago is still valid and helps scientists spot trends that would otherwise be lost in the flurry of new data they are trying to collect.  And sometimes, that data holds something interesting.  Such is the case when a group of scientists took a look at the infrared data of Neptune’s atmosphere and found not one but two weird changes happening.

We’ve discovered thousands of exoplanets and are likely to find many thousands more of them. While the wide variety of planets we’ve found are scientifically interesting in their own right, what lurks behind all these discoveries is the search for a world that could harbour life.

Humans have long dreamed of setting foot on Mars or beyond, and the advances by companies like SpaceX and Blue Origin means perhaps the dream could be closer than ever to becoming reality. But as it stands now, sending astronauts on long-duration missions to other worlds would be impossible because of the hazardous radiation levels in space, outside of Earth’s protective magnetic field.

In the coming decade, NASA plans to conduct the first crewed missions to Mars. Whereas robotic missions have provided images of the Martian surface for decades, this will be the first time human beings experience the Red Planet directly. In anticipation of these missions, NASA and its commercial partners (Epic Games and Buendea) have come together with HeroX – the leading platform for crowdsourced solutions – to launch the NASA MarsXR Challenge.

Lunar exploration has advanced considerably in the last two decades, with more countries sending robotic orbiters, landers, and rovers to the surface than ever before. These missions have taught us much about the Moon’s geological evolution, composition, environment, and resources. In a few years, this information will prove vital as NASA sends the first astronauts to the Moon since the Apollo Era (as part of the Artemis Program). They will be followed by many more crewed missions, which will eventually lead to the creation of lunar bases.

Spin Google Earth around until you’re looking down at the nation of Oman. Ancient rock in that country is the backdrop for a new study with consequences for our search for life. Water reacts with this rock to produce hydrogen, which could be an energy source for bacteria. Could this happen on other worlds?

The Ingenuity Mars Helicopter is providing scientists a look at what is on the road ahead for the Perseverance rover. And acting as a scout, Ingenuity can tell the team what places to avoid, too.

Despite decades of study, black holes remain one of the most powerful and mysterious celestial objects ever studied. Because of the extreme gravitational forces involved, nothing can escape the surface of a black hole (including light). As a result, the study of these objects has traditionally been confined to observing their influence on objects and spacetime in their vicinity. It was not until 2019 that the first image of a black hole was captured by the Event Horizon Telescope (EHT).

Rocket Lab has just joined SpaceX in the club of space companies that can launch an orbital-class rocket booster and bring it back alive.

In April of 2019, the international astronomical consortium known as the Event Horizon Telescope (EHT) made headlines worldwide when it announced the first-ever image of a black hole. Specifically, the image showed the glowing disk surrounding the supermassive black hole (SMBH) at the center of the M87 galaxy. In 2021, they followed up on this by acquiring an image of the core region of the Centaurus A galaxy and the radio jet emanating from it.

The images released by the James Webb Space Telescope team last week aren’t officially ‘first light’ images from the new telescope, but in a way, it feels like they are. These stunning views provide the initial indications of just how powerful JWST will be, and just how much infrared astronomy is about to improve.

If there are so many galaxies, stars, and planets, where are all the aliens, and why haven’t we heard from them? Those are the simple questions at the heart of the Fermi Paradox. In a new paper, a pair of researchers ask the next obvious question: how long will we have to survive to hear from another alien civilization?

This is reminiscent of going down slide on the playground – and then immediately getting back in line to go down again. Except in space.

In the coming decade, NASA and China plan to send the first crewed missions to Mars. This will consist of both agencies sending spacecraft in 2033, 2035, 2037, and every 26 months after that to coincide with Mars being in “Opposition” (i.e., when Earth and Mars are closest in their orbits). The long-term aim of these programs is to establish a base on Mars that will serve as a hub that accommodates future missions, though the Chinese have stated that they intend for their base to be a permanent one.
