You’re looking at a 300-megapixel photo of our Sun. Astrophotographer Andrew McCarthy used a specially modified telescope, taking over 150,000 individual photos and combing them into this magnificent image.

Can planets form around massive, hot stars? Some astronomers think they can’t. According to the evidence, planets around stars exceeding three solar masses should be rare, or maybe even non-existent. But now astronomers have found one.
Patterns in nature often occur in more than one place. Spirals, symmetry, and chaos all impact natural phenomena, from the shape of a shell to the course of a river. So it shouldn’t come as a surprise that one of the most famous and fundamental shapes from biology also appears in astrophysics. Yes, scientists have found a double-helix structure in the magnetic field of M87. And it looks just like a super enlarged DNA strand.
Despite all its wonderful properties, water isn’t the only resource needed for space exploration. Carbon is another important ingredient for many necessary materials, such as steel, rocket fuel, and biomaterials. Therefore, proponents of lunar exploration should be excited by a recent study led by Dr. Norbert Schorghofer of the Planetary Science Institute that found natural “cold traps” for carbon dioxide in some of the permanently shadowed craters of the moon.
We’ve covered plenty of the Parker Solar Probe’s exploits here at UT, but it keeps breaking new records almost every month. Now, with its newest flyby, it has gotten closer to the Sun than ever before, breaking its own record from previous flybys.
Welcome to another edition of Constellation Friday! Today, in honor of the late and great Tammy Plotner, we take a look at “the Furnace” – the Fornax constellation. Enjoy!
One of the greatest cosmological mysteries facing astrophysicists today is Dark Matter. Since the 1960s, scientists have postulated that this invisible mass accounts for most of the matter in the Universe. While there are still many unresolved questions about it – i.e., What is it composed of? How do we detect it? What evidence is there beyond indirect detection? – we have managed to learn a few things about it over time.
On Oct. 12th, 2021, after years of waiting and cost overruns, the James Webb Space Telescope (JWST) finally arrived safely at Europe’s Spaceport in Kourou, French Guiana. The crews began unboxing the next-generation observatory and getting it ready for integration with the Ariane 5 rocket that will take it to space. Then, an “incident” occurred where a clamp band suddenly released, sending vibrations throughout the facility. Once again, the JWST’s launch date was pushed back while crews investigated the source of the problem.
A new mission has launched to study some the most intriguing secrets of the universe. No, not THAT spacecraft (JWST is scheduled for launch on December 22). Another new and exciting mission is called Imaging X-ray Polarimetry Explorer (IXPE) and it will allow scientists to explore the hidden details of some of the most extreme and high-energy objects in the cosmos, such as black holes, neutron stars, pulsars and dozens of other objects.
In the history of space exploration, there are a handful of missions that have set new records for ruggedness and longevity. On Mars, the undisputed champion is the Opportunity rover, which was slated to run for 90 days, but remained in operation for 15 years instead! In orbit around Mars, that honor goes to the 2001 Mars Odyssey, which is still in operation 20 years after it rendezvoused with the Red Planet.
An asteroid striking Earth is a genuine possibility. There are tens of thousands of asteroids classified as Near-Earth Asteroids (NEAs), and we’re finding around 3,000 more each year. The number of new detections will see an uptick in the next few years as better survey telescopes come online.
Ion thrusters have played second fiddle to chemical rockets for most of the history of space exploration. Part of that is because of their inability to launch payloads into orbit. But in space, their high thrust-to-weight ratio has plenty of appeal. Other features have held the technology back, including the difficulty of working with the thruster’s fuel source – xenon. Now, a team of engineers and scientists from ThrustMe, a French start-up that focuses on developing advanced propulsions systems, have developed an ion thruster that works on an entirely new and much easier to use material – iodine.
The latest images from the Juno mission at Jupiter includes views of giant storms and vortexes on the gas giant world in amazing detail.
Since the 1970s, scientists have known that within the cores of most massive galaxies in the Universe, there beats the heart of a Supermassive Black Hole (SMBH). The presence of these giant black holes causes these galaxies to be particularly energetic, to the point where their central regions outshine all the stars in their disks combined – aka. Active Galactic Nuclei (AGN). The Milky Way galaxy has its own SMBH, known as Sagitarrius A*, which has a mass of over 4 million Suns.
Some planets orbit their stars so closely that they have extremely high surface temperatures and extremely rapid orbits. Most of the ones astronomers have found are Hot Jupiters— planets in the size range of Jupiter and with similar compositions as Jupiter. Their size and proximity to their star make them easier to spot using the transit method.
How do you power a super advanced alien civilization? Soak up a star. We harness the power of the Sun using solar panels. What if you were to scale this idea to astronomical proportions? Surround an entire star with solar collecting structures or satellites to power your sprawling alien galactic empire. Such massive structures are known as a “megastructures” – in this case a “Dyson Sphere.” We are already trying to detect possible megastructures in space using the dimming of a star and the glow of megastructure components in infrared light. But recent research provides a new detection method – a Dyson Sphere may cause its host star to swell and cool.
Gamma rays are useful for more than just turning unassuming scientists into green-skinned behemoths. They can also shine a light on the deaths of some of the earliest stars in the universe. More accurately, they are some of the light caused by the deaths of the earliest stars in the universe. Now, a team of scientists led by Nicholas White of George Washington University, and formerly of NASA’s Goddard Space Flight Center, has proposed an observatory mission that would scan the sky for evidence of Gamma-ray bursts (GRBs) and use them to understand the early universe.
Japanese billionaire Yusaku Maezawa is set to begin his first space adventure — an 11-day visit to the International Space Station that could serve as the warmup for a round-the-moon trip to come.
Astronomers have a new tool to help them understand giant stars. It’s a detailed study of the precise temperatures and sizes of 191 giant stars. The authors of the work say that it’ll serve as a standard reference on giant stars for years to come.
On December 2nd, 2021, the commercial space company Rocket Lab unveiled the detailed architecture of their Neutron rocket for the first time. In a live-streamed event, the company showcased all the new elements that will make this “megaconstellation” launcher a serious contender in the coming years. These include updated details about the rocket’s design, materials, propulsion, and reusability architecture.
