Remember all the fuss about the “doorway on Mars” from just last week? Well, this week, NASA issued some more information about the rock mound where the Curiosity rover snapped a pic showing a fracture hole in the rock. It looks like a door, but it’s not.

Ever wonder what it would be like to fly through the Orion Nebula with all its newborn stars? Or buzz through the California Nebula? Of course, we’ve seen simulated “fly-throughs” of nebulae in sci-fi TV and movies and on planetarium domes. But, what if we had a warp-speed spaceship and could chart a path through the real thing? The first thing we’d need is accurate data about that region of space. That’s where a 3D model with precise distance measurements to stars and other objects would come in really handy.

It might be hard to fathom now, but the human exploration of the solar system isn’t going to stop at the Moon and Mars. Eventually, our descendants will spread throughout the solar system – for those interested in space exploration, the question is only of when rather than if. Answering that question is the focus of a new paper released on arXiv by a group of researchers from the US, China, and the Netherlands. Their approach is highly theoretical, but it is likely more accurate than previous estimates, and it gives a reasonable idea of when we could expect to see humans in the outer solar system. The latest they think we could reach the Saturnian system is 2153.

As of this article’s writing, NASA has indicated that 5,030 extrasolar planets have been confirmed in 3,772 systems, with another 8,974 candidates awaiting confirmation. With next-generation instruments like the James Webb Space Telescope (JWST) coming online, the number and diversity of confirmed exoplanets are expected to grow exponentially. In particular, astronomers anticipate that the number of known terrestrial planets and Super-Earths will drastically increase.
In the coming years, the opportunities for exoplanet studies will increase considerably as thousands more are discovered using various methods. In a recent study, a team led by the Chinese Academy of Sciences (CAS) described a new space-telescope concept known as the Closeby Habitable Exoplanet Survey (CHES). This proposed observatory will search for Earth-like planets in the habitable zones (HZs) of Sun-like stars within approximately 33 light-years (10 parsecs) using a method known as micro-arcsecond relative astrometry.

Mars is well-known for its seasonal dust storms, which can sometimes grow to encompass the entire planet. In June 2018, the dust storms became so severe that they obscured most of the planet’s surface, causing NASA to lose contact with Opportunity, which eventually proved fatal to the record-breaking rover. Understanding these storms and what causes them is critical to ensuring that solar-powered robotic missions continue to operate and future crewed missions can remain safe.
Specifically, scientists are looking for seasonal changes (i.e., changes in absorbed solar energy and temperature increases) that trigger dust storms and cause them to combine and grow. In a recent study conducted by researchers from the University of Houston, they could result from seasonal energy imbalances in the amount of solar energy absorbed and released by the planet. These findings could lead to a new understanding of the Red Planet’s climate and atmosphere.

Can watching a video give you motion sickness? If so, a commercial launch company called SpinLaunch just released a video that is sure to. The video is from the first camera ever attached to one of the company’s test payloads, and boy is it spectacular, though it might indeed be nausea-inducing in some people.

Take a good look at the latest image provided by the Hubble Space Telescope. It shows a huge elliptical galaxy called NGC 474 that lies about 100 million light-years away from us. At about two and a half times larger than our Milky Way Galaxy, it’s really a behemoth. Notice its strange structure—mostly featureless and nearly round, but with layered shells wrapped around the central core. Astronomers want to know what caused these shells. The answer might be in what this galaxy represents: a vision of the future Milky Way and the Andromeda Galaxy.

NASA is sending astronauts back to the Moon by the end of this decade, and hope to send humans to Mars sometime in the 2030s. Growing food in space using in-situ resources is vital if astronauts are to survive on both the Moon and Mars for the long-term. Growing plants in space using Earth soil is nothing new, as this research is currently ongoing onboard the International Space Station (ISS). But recent research carried out on Earth has taken crucial steps in being able to grow food in space using extraterrestrial material that we took from the Moon over 50 years ago.

If you were able to witness the lunar eclipse on May 15-16, 2022, the view of the dark red Moon was stunning. But what would such an eclipse look like from space?
Wonder no longer. ESA/Italian astronaut Samantha Cristoforetti captured a series of photos of the lunar eclipse from her unique vantage point aboard the International Space Station (ISS).

Be sure to watch the skies on the last morning of May, for a possible Tau Herculid meteor outburst.
If predictions hold true, we may be in for a rare meteor outburst from an obscure meteor shower on May 31st topping a thousand meteors per hour… or we may see nothing at all. Welcome to the wonderful world of meteor shower predictions and prognostications.
