Zooming Into the Young Star HD 135344B and Its Planet Candidate SciTech Daily 2025-08-11 | scitechdaily.com/astronomers-just-caught-a-giant-baby-planet-sculpting-spirals-in-spaceThis video zooms into HD 135344B, a young star located around 440 light-years away. The star is surrounded by a disc of dust and gas with prominent spiral features. New observations obtained with ESO’s Very Large Telescope (VLT) may have unveiled a planet that could be sculpting these features. The video combines images taken with different telescopes at different times and various wavelengths. The journey begins with a wide view of the night sky in visible light. As we approach HD 135344B we see three images of the immediate vicinity of the star. First, an image of the star’s dusty disc taken with the Atacama Large Millimeter/submillimeter Array (ALMA). Then, an infrared view of the spiral arms within the disc, captured with the SPHERE instrument at the VLT. Finally, a new infrared image revealing a candidate planet, taken with the VLT’s new ERIS instrument. Credit: ESO/L. Calçada/N.

Millisecond Pulsar With Magnetic Field Structure SciTech Daily 2025-08-11 | scitechdaily.com/nasa-just-discovered-where-these-mysterious-space-x-rays-really-come-fromThis animation zooms into a neutron star and its accretion disk to show a millisecond pulsar in close-up.A pulsar is a rapidly rotating neutron star that emits pulses of radiation (such as X-rays and radio waves) at regular intervals. A millisecond pulsar is one with a rotational period between 1 and 10 milliseconds, or from 60,000 to 6,000 revolutions per minute. Pulsars form in supernova explosions, but even newborn pulsars don’t spin at millisecond speeds, and they gradually slow down with age. If, however, a pulsar is a member of a binary system with a normal star, gas transferred from the companion can spin up an old, slow pulsar to the millisecond range.Credit: NASA

NASAs Mars Reconnaissance Orbiter Performing Very Large Roll SciTech Daily 2025-08-11 | scitechdaily.com/nasa-flips-a-mars-orbiter-upside-down-and-discovers-a-hidden-worldThis animation depicts NASA's Mars Reconnaissance Orbiter (MRO) performing what's called a "very large roll": a 120-degree roll that can increase the capabilities of the spacecraft's subsurface radar instrument, called Shallow Radar, or SHARAD. Very large rolls boost SHARAD's signal by 10 times or more, giving scientists a clearer and deeper look below the Martian surface than MRO has ever had before.The orbiter was designed to roll up to 30 degrees in any direction so that it can point its instruments at surface targets. These standard rolls give cameras like the High-Resolution Imaging Science Experiment (HiRISE) prime viewing at the front of MRO at the expense of SHARAD, which has an antenna mounted at the back of the orbiter. While this setup helps the cameras, it also means that radio signals SHARAD pings onto the surface below encounter parts of the spacecraft, interfering with the signals and resulting in images that are less clear.In 2023, the team decided to try developing 120-degree rolls – the very large rolls – that rotate SHARAD's antenna toward the planet and provide the radio waves an unobstructed path to the surface. That lets the radar's signals reach deeper and get a clearer picture of rocks, sand, and geologic layers underground. It also helps SHARAD look for water ice in the near-subsurface that could be accessed by astronauts to produce rocket propellant for the trip home and is important for learning more about the climate, geology, and potential for life at Mars.Credit: NASA/JPL-Caltech

What Is the Origin of the Moon? SciTech Daily 2025-06-24 | scitechdaily.com/the-moons-explosive-backstory-how-a-planetary-smash-spawned-our-nightlightThe Moon has been circling the Earth for over four billion years, but where did it come from? In this video, Ralf Jaumann, planetary geologist at the German Aerospace Centre, DLR, discusses the four theories that could explain the origin of the Earth-Moon system.There are four theories about the origin of the Earth-Moon system. The first is that Earth captured a celestial body in its orbit. Another possibility is that a rapidly rotating Earth could have thrown material out to form the Moon around it. A third theory is that Earth and the Moon formed at the same time out of the same material. Today, most scientists believe the Moon is ‘Earth's child’ – a large body collided with Earth, destroying our planet’s mantle and sending material into orbit from which the Moon formed. This ‘big splash’ theory would explain why the Moon’s rocks are similar to those on Earth. Credit: ESA
NASA’s Chandra Sees Surprisingly Strong Black Hole Jet at Cosmic “Noon” SciTech Daily 2025-06-16 | scitechdaily.com/nasa-detects-11-billion-year-old-black-hole-jet-lit-by-the-big-bangA black hole has blasted out a surprisingly powerful jet in the distant universe, according to a new study from NASA’s Chandra X-ray Observatory. This jet exists early enough in the cosmos that it is being illuminated by the leftover glow from the Big Bang itself.Astronomers used Chandra and the Very Large Array, an array of radio dishes in New Mexico, to study this black hole and its jet. They are seeing this black hole at a period they call “cosmic noon,” which occurred about three billion years after the universe began. During this time most galaxies and supermassive black holes were growing faster than at any other time during the history of the universe.Scientists are hoping to use this jet to probe questions about how black holes helped shape their surroundings during this critical era in cosmic history. They are finding that some black holes may carry a bigger punch at this stage in the universe than they thought.The researchers identified and then confirmed the existence of two different black holes with jets over 300,000 light-years long. The two black holes are 11.6 billion and 11.7 billion light-years away from Earth, respectively. The team discovered that one of the jets is remarkably powerful, because they found it carries roughly half as much energy as the intense light from hot gas orbiting the black hole.Only Chandra could detect these very distant black holes because they are very close together on the sky. Even then, Chandra needed the photons to be boosted by the leftover glow from the Big Bang — known as the cosmic microwave background — to get a signal.As the electrons in the jets fly from the black holes, they move through the sea of cosmic microwave background radiation and collide with microwave photons. The cosmic microwave background was much denser in the very early Universe than it is now. These collisions boost the energy of the photons up into the X-ray band to be detected by Chandra.By combining the X-ray and radio data, the researchers calculated that the particles in the jets are moving at between 95% and 99% of the speed of light for one jet and between 92% and 98% of the speed of light for the other. The researchers were also able to measure the magnetic fields of these jets, providing more clues about the nature of these very distant and very powerful black hole jets.Credit: NASA/CXC/A. Hobart

Time-Lapse Shows a Complexly Shaped Plasma Stream Traveling at Almost 100 Kilometers per Second SciTech Daily 2025-06-09 | scitechdaily.com/raindrops-on-a-fireball-sharpest-ever-look-inside-the-suns-wild-coronaThis time-lapse movie shows the formation and collapse of a complexly shaped plasma stream traveling at almost 100 kilometers per second in front of a coronal loop system. This is likely the first time such a stream, which the scientists refer to as “plasmoid”, has been observed, leaving them wondering about the physical explanation of the observed dynamics. This video was taken by the Goode Solar Telescope at Big Bear Solar Observatory using the new coronal adaptive optics system Cona. The video shows the hydrogen-alpha light emitted by the solar plasma. The video is artificially colorized, yet based on the color of hydrogen-alpha light, and darker color is brighter light.Credit: Schmidt et al./NJIT/NSO/AURA/NSF

Time-Lapse Video of a Prominence Above the Solar Surface Reveals Its Turbulent Restructuring SciTech Daily 2025-06-09 | scitechdaily.com/raindrops-on-a-fireball-sharpest-ever-look-inside-the-suns-wild-coronaThis time-lapse video of a prominence above the solar surface reveals its rapid, fine, and turbulent restructuring with unprecedented detail. The Sun’s fluffy-looking surface is covered by “spicules”, short-lived plasma jets, whose creation is still subject of scientific debate. The streaks on the right of this image are coronal rain falling down onto the Sun’s surface.

Time-Lapse Video of the Highest Resolution Images Ever Made of Coronal Rain SciTech Daily 2025-06-09 | scitechdaily.com/raindrops-on-a-fireball-sharpest-ever-look-inside-the-suns-wild-coronaCoronal rain forms when hotter plasma in the Sun’s corona cools down and becomes denser. Like raindrops on Earth, coronal rain is pulled down to the surface by gravity. Because the plasma is electrically charged, it follows the magnetic field lines, which make huge arches/loops, instead of falling in a straight line. This time-lapse video is composed of the highest resolution images ever made of coronal rain. The scientists show in the paper that the strands can be narrower than 20 kilometers.
