It looks like South Korea just joined the most exclusive club on the planet! With the launch of its Korea Satellite Launch Vehicle II (KSLV-II aka. the “Nuri” rocket) on June 21st, the country became the latest nation to demonstrate its ability to build and launch its own rockets to space. This was the Nuri’s second launch attempt, which took place eight months after the first attempt failed to deliver a test satellite to orbit back. This time, the rocket managed to reach space and deliver a payload of satellites, making South Korea the eleventh nation to launch from its soil and the seventh to launch commercial satellites.

SN 1054 was one of the most spectacular astronomical events of all time. The supernova explosion eventually formed what is today known as the M1 – the Crab Nebula. But in 1054 AD, the year it occurred, it was an ultrabright star in the sky and one of only eight recorded supernovae in the history of the Milky Way. However, it was only noted by half of the literate world. Primarily written about in the East, especially in China, SN 1054 was almost wholly absent from the Western record. Except, potentially, for a subtle hint at it in the most unlikely of places – some Byzantine coins.

Located in the Northern Cape of South Africa, the MeerKAT telescope consists of 64 powerful radio antennas dedicated to probing the mysteries of the Universe. This facility is a precursor to the future Square Kilometer Array Observatory (SKAO), which will consist of MeerKAT and the Hydrogen Epoch of Reionization Array (HERA) in South Africa and the Australian SKA Pathfinder (ASKAP) and Murchison Radio-astronomy Observatory in Australia. A primary aim of the SKAO is to understand the matter content of the Universe and what mechanisms are driving its evolution and expansion.

The Universe’s giant galaxies pose a thorny problem for astronomers. The galaxies have grown large somehow, and the only things that can make a galaxy giant are probably other galaxies. So mergers must have played an important role.

The 500-Meter Aperture Spherical Telescope (FAST), (aka. Tianyan, “Eye of Heaven”), is the largest radio observatory in the world. Since the observatory became operational in January 2020, this facility has made significant contributions to radio astronomy and the Search for Extraterrestrial Intelligence (SETI). In particular, the observatory has been instrumental in detecting Fast Radio Burts (FRBs) and other cosmic phenomena that could be (but probably aren’t) possible indications of extraterrestrial communications.

A newly discovered supercluster of galaxies is so distant that astronomers say its light has been traveling for over twelve billion years to reach telescopes on Earth. But this cluster, named SPT2349 ?56 is gigantic, and so old that it is actually classified as a proto-cluster of galaxies, meaning it might be one of the earliest large clusters of galaxies in our Universe. It is also one of the most actively star-forming proto-clusters known.

In the decades-long search for extraterrestrial intelligence, there has never been confirmed evidence of an alien signal. There have, however, been a few tantalizing mysteries. Perhaps the greatest of these is known as the Wow Signal.

Pluto’s largest moon, Charon, started off as a beautiful, smooth red grape until someone came along, mostly peeled it, tried to smoosh it, then just gave up and walked away, leaving the poor moon to look like the absolute travesty that it is. Okay, so maybe that’s not exactly what happened, but Charon just looks like a mess and scientists want to know why. Never mind its smooshed equator, but what’s the deal with its red cap? Where did it come from and why is it red?

The earliest mention of asteroid mining might be in a story from 1898 titled “Edison’s Conquest of Mars,” by Garrett Serviss. In that story, Martians attack Earth, killing tens of thousands and destroying New York City. Earth retaliates and sends an armada to Mars. While travelling, the armada comes across an asteroid that the Martians are mining. The asteroid is a rubble pile of gold nuggets.

It’s here! The third and largest data release (DR3) from the ESA’s Gaia Observatory has officially been made public. As promised, the DR3 contains new and improved details for almost two billion stars in our galaxy, including the chemical compositions, temperatures, colors, masses, ages, and the velocities at which stars move. The release coincided with a virtual press event hosted by the Gaia Data Processing and Analysis Consortium (DPAC) on June 13th, which featured ESA officials and guest speakers who addressed the significance of the new data.

From orbit, this landscape on Mars looks like a lacy honeycomb or a spider web. But the unusual polygon-shaped features aren’t created by Martian bees or spiders; they are actually formed from a ongoing process of seasonal change from created from water ice and carbon dioxide.

Our Moon is a fascinating world that has captivated us since time immemorial. Long before the first telescope was invented, ancient humans used the Moon as a calendar in the sky, with evidence that lunar timekeeping was around as early as 25,000, 30,000, and even 35,000 years before the present. Long before humanity had written language, lived in organized cities, and worshipped structured religions, the Moon was one of humanity’s first timepieces. It wasn’t until the telescope was invented that our Moon became an object of scientific curiosity, with the sketches by Galileo Galilei giving us a new perspective on our nearest celestial neighbor. As science advanced, so did our understanding of the Moon. While the Apollo missions were successful in teaching us about the geology of the Moon, it wasn’t until 2009 when the LCROSS impact probe onboard the Lunar Reconnaissance Orbiter deliberately crashed into a dark crater on the Moon’s south pole and detected 155 kilograms of water as it flew through the ejecta plume before ultimately crashing into the lunar surface.

For nearly 30 years Geoff Notkin has traveled the world in search of meteorites, those ancient relics from outer space that have fallen to Earth. He shared his adventures on the Science Channel series “Meteorite Men,” and through lectures and appearances across almost every continent, he has sparked interest in space science and exploration. He has been a devoted meteorite hunter and collector, amassing a large collection. But now, after much deliberation, Notkin has decided to auction off some of his personal meteorite collection, as well as other personal items.

In 2014, the Japan Aerospace Exploration Agency (JAXA) dispatched its Hayabusa2 spacecraft to rendezvous with 162173 Ryugu, a Near-Earth Asteroid (NEA) that periodically passes close to Earth. In 2018, this sample-return mission reached Ryugu and spent the next year and a half studying its surface and obtaining samples from its surface and subsurface. By 2020, these samples made it back to Earth, where scientists began analyzing them in the hopes of learning more about the early history of the Solar System and answering key questions about the origins of life.

Comets that venture close to the Sun can transform into something beautiful, but sometimes they encounter incineration if they get too close. Of the various types of comets that orbit close to the Sun, astronomers had never seen the destruction of the type classified as “near-Sun” comets. But thanks to a variety of telescopes on summit of Mauna Kea in Hawai?i, scientists have now captured images of a periodic rocky near-Sun comet breaking apart. They say the disintegration of this comet could help explain the scarcity of such periodic near-Sun comets.

A young galaxy with the catchy, roll-off-the-tongue name A1689-zD1 has experts in galactic formation talking. Recent observations show that this galaxy, seen as it would have looked just 700 million years after the Big Bang, is larger than initially believed, with significant outflows of hot gas from its core, and a halo of cold gas emanating from its outer rim. A1689-zD1 is considered representative of young ‘normal’ galaxies (as opposed to ‘massive’ galaxies), and the new observations suggest that the adolescence of normal galaxies may be more rambunctious than previous models suggest.

Ever since childhood, we were all told to never play with fire. Despite it being relevant to our everyday lives, to include heating our homes and water, cooking our food, producing electricity, and more, fire is extremely dangerous. We were all indoctrinated more with how to put out fires instead of how to start one. We’ve all been told about its destructive properties if mishandled, and that fire needs to be controlled. One of the perks of adulthood, and especially being a scientist, is you get paid to play with fire. Despite fire’s complexities, there’s still a lot we don’t know about its behavior. With more and more of humanity traveling to space and living in microgravity, it’s important to learn about how fire behaves in this unique environment to better prepare ourselves for worst case scenarios. But what if we could also control fire so it’s not as dangerous and less destructive to the environment back here on Earth?

When it comes to exciting places to look in the sky, the Tarantula Nebula is hard to beat. It’s got cloudy star-forming regions, hot young stars, and star clusters. It’s one of the brightest and most active star birth areas in the Milky Way’s neighborhood. It’s also got an amazing collection of massive stars. That range of stellar activity makes the Tarantula almost the perfect laboratory to study the mechanics of star formation.

A couple of years ago, Betelgeuse generated much interest when it started dimming. That caught the attention of astronomers worldwide, who tried to understand what was happening. Was it about to go supernova?

Things may seem quiet and peaceful in the Andromeda Galaxy when you gaze at it in the sky. However, if you know what to look for, there’s evidence of a violent rumble in this galaxy’s past. That’s the takeaway from research by Ivanna Escala, an astronomer at Carnegie Institution for Science in Pasadena. She found telltale clues for a merger a few billion years ago. That’s when Andromeda actively cannibalized another galaxy.

The Perseverance rover has begun exploring a region that looks a little like Monument Valley in Arizona and Utah in the US, or perhaps like a set on an old sci-fi movie. The rock formations in this area on Mars are stunning in their varied and sometimes absurd shapes and structures. One wonders what took place here eons ago to create the weird variety of formations.
