Uranus is Leaking Heat Like Never Before — Experts are Baffled!
According to a recent study, published Monday in Geophysical Research Letters, Uranus does have an internal heat source like its planetary siblings, which may have led scientists to misinterpret the data from Voyager 2. Uranus emits 12.5% more internal heat than it takes in from the Sun.
Compared to the other three giant planets, which release over 100% of the solar energy they receive, that is still a significant reduction in heat. However, the study that analyzed decades' worth of archival data on the ice giant shows that Uranus doesn't deviate significantly from the general knowledge of scientists regarding the formation and evolution of giant planets.
The researchers examined data on Uranus's global energy balance over an 84-year orbit of the Sun in order to arrive at this conclusion. The team discovered significant seasonal swings caused by the planet's erratic variations in sunlight exposure after combining this observational data with computational models.
The latest results align with a previous study on Uranus' energy balance that was published in May in the Monthly Notices of the Royal Astronomical Society.
The study, however, said that neither study provides a definitive explanation for why Uranus's internal heat is significantly lower than that of the other gas and ice giants. According to a statement from the researchers, Uranus might have had a "different interior structure or evolutionary history compared to the other giant planets."
Additionally, the study discovered that Uranus's energy levels fluctuate in accordance with its 20-year seasons. According to the study, these variations "provide observational constraints that can be used to develop theories of planetary formation for giant planets," in conjunction with the planet's heat budget.
As a result, Uranus is addressed as well as questioned in the paper, which the researchers point to as a compelling argument for further NASA exploration of the icy planet.
Liming Li, study co-author and physicist at the University of Houston, said, "By uncovering how Uranus stores and loses heat, we gain valuable insights into the fundamental processes that shape planetary atmospheres, weather systems, and climate systems," adding, "These findings help broaden our perspective on Earth's atmospheric system and the challenges of climate change."

Uranus is Leaking Heat Like Never Before — Experts are Baffled!
Back in 1986, Voyager 2 had discovered a surprisingly low amount of internal heat from Uranus when it passed the planet. Since then, scientists have thought of Uranus as the odd man out of the family of giant planets in our solar system, which also includes Jupiter, Saturn, and Neptune. These planets all have a tendency to release more heat into space than they take in from the sun. According to a recent study, published Monday in Geophysical Research Letters, Uranus does have an internal heat source like its planetary siblings, which may have led scientists to misinterpret the data from Voyager 2. Uranus emits 12.5% more internal heat than it takes in from the Sun.

Earth Spins Faster on Wednesday, Making July 9 the Shortest Day in History; Scientists Explain Why
Earth will spin faster on Wednesday (July 9), making it the shortest day in recorded history because of the Moon's position, according to scientists. On average, the planet completes its full rotation on its axis, from the Sun's point of view, in exactly 86,400 seconds, with a slight difference in a millisecond or so. In other words, 86,400 seconds is equal to 24 hours. However, Earth could complete a full rotation around the Sun on Wednesday (July 9) nearly 1.30 milliseconds faster than on average days. The celestial speed up will range between 1.3 and 1.6 milliseconds less than the usual 24 hours on Wednesday. So, Wednesday might feel shorter than the other days with lots of things to do and no time to finish them. Experts say that this change is due to a scientific phenomenon, which results in the Earth's faster spinning. The blue planet will spin faster this summer due to the Moon's position, they explained. When the position of the Moon is far to the south or north of Earth's equator, the planet spins faster. Other reasons for this phenomenon could be anything, ranging from natural disasters to seasonal changes. This disturbance in the force will be the sixth of its kind since 2020. Shortest Days in Recorded History A millisecond is considered less than the amount of time required to blink an eye, which could last around 100 milliseconds. That's why the tiny time difference may not be imperceptible to humans. These tiny day-to-day variations in the Earth's spinning are measured with the help of atomic clocks, introduced in the 1950s. The length of the day is calculated by measuring the number of milliseconds Earth needs to complete a full rotation on its axis. Scientists found the blue planet creating a new record every year since 2020. Until 2020, the shortest recorded length of the day was -1.05 milliseconds. It means Earth completed a full rotation around the Sun in 1.05 milliseconds less than 86,400 seconds. But the planet managed to break the record by half a millisecond every year. Here are the Shortest Days Recorded in History Since 2020: July 19, 2020 - 1.47 ms July 9, 2021 - 1.47 ms June 30, 2022 - 1.59 ms July 16, 2023 - 1.31 ms July 5, 2024 - 1.66 ms Experts said that Tuesday (July 22) and Tuesday (August 5) could be similarly short days. On Tuesday (July 22), the planet is expected to complete a full rotation on its axis in 1.38 milliseconds less than its average 86,400 seconds. Similarly, on Tuesday (August 5), Earth could complete a full rotation around the Sun by 1.51 milliseconds less than 86,400 seconds. International Earth Rotation and Reference Systems Service (IERS), which is responsible for handling the negative leap second, revealed that this phenomenon could lead to the first adjustment to the clock, expected to be made in 2029. "This is an unprecedented situation and a big deal. It's not a huge change in the Earth's rotation that's going to lead to some catastrophe or anything. However, it is something notable. It's yet another indication that we're in a very unusual time," New York Post quoted Duncan Agnew, a geophysicist at the Scripps Institution of Oceanography at the University of California, San Diego.

NASA Shares First Complete View of Unusual Peanut-Shaped Asteroid Donaldjohanson
Finally, scientists working on NASA's Lucy mission are completing the process of fine-tuning the data collected by the spacecraft's encounter with Donaldjohanson, an asteroid in the main asteroid belt of our solar system, on April 20. And it's just as peanut shaped as we initially thought. At a distance of roughly 600 miles (960 kilometers), Lucy's Long Range Reconnaissance Imager captured a picture of Donaldjohansson earlier this year as it swiftly flew by it. The smallest features visible were about 130 feet (40 meters) across, which is an amazing close-up given the size of everything we see in space. Unfortunately, the Sun's position behind Lucy made the asteroid's finer details less noticeable. Even so, the close visit is crucial because it enables scientists to meticulously examine the surface's details after correcting for brightness. Hal Levison, Lucy's principal investigator, in an earlier press release about the asteroid, said, "Asteroid Donaldjohanson has strikingly complicated geology". About 150 million years ago, two smaller objects collided in space, giving Donaldjohansson its lumpy shape. Given that smaller asteroids in the solar system have a similar shape, Donald Johanson's findings may help us comprehend a wide range of other celestial objects. "As we study the complex structures in detail, they will reveal important information about the building blocks and collisional processes that formed the planets in our Solar System," Levison added. The Lucy mission's itinerary includes visiting the eight Trojan asteroids that orbit Jupiter in the same orbit as the Sun, and Donaldjohansson is not its primary goal. However, NASA's Erin Morton said earlier this week that Lucy's Donaldjohanson encounter—as well as the November 2023 flyby of asteroid Dinkinesh—is a great "dress rehearsal" for Lucy as it continues its journey toward the cooler, outer regions of the solar system. The next significant event for Lucy is scheduled for August 2027, when the spacecraft will begin exploring the Jupiter Trojan asteroids in earnest. Eurybates is a carbonaceous asteroid so large that it has its own satellite, Queta.
