The Rosalind Franklin mission’s chance of finding evidence of past life on Mars has been boosted by two studies that show that the rover won’t have to travel far to find materials potentially laden with organic molecules. Instead, natural processes could bring those materials to the rover, as revealed in two separate presentations at the EPSC–DPS2025 Joint Meeting in Helsinki this week.

LEOs who are already credentialed in the state will get a $25,000 bonus upon hiring, $12,500 after one year of service and another $12,500 after two years of service
Just over a year ago, NASA made a remarkable announcement. The Perseverance rover had found potential signs of ancient life on Mars. Now, the technical details behind that discovery have been published in a Nature paper that, despite its rather modest wording, may ultimately prove to be among the most significant in the history of science.
The TV series Alien:Earth has introduced a number of new creatures to the much loved, albeit terrifying, Alien franchise.
Ten years ago, scientists heard the universe rumble for the first time. That first discovery of gravitational waves proved a key prediction from Albert Einstein’s theory of general relativity and began a new era of astronomy.
Science advances through data that don’t fit our current understanding. At least that was Thomas Kuhn’s theory in his famous On the Structure of Scientific Revolutions. So scientists should welcome new data that challenges their understanding of how the universe works.
Astronomers have discovered what they think may be another moon orbiting a distant dwarf planet called Quaoar. This small, icy, egg-shaped planet in the far reaches of our solar system, beyond Neptune, is already known to have two rings and a moon, but this discovery was unexpected and accidental.
A newly discovered set of mathematical equations describes how to turn any sequence of random events into a clock, scientists at King’s College London reveal. The paper is published in the journal Physical Review X.
In the universe, thermonuclear fusion is a common reaction: it is the source of energy for stars. On Earth, producing energy using this process is difficult due to problems with controlling the plasma emitting significant amounts of energy. Of critical importance here is the knowledge of the current state of the plasma and the power released in nuclear reactions. In the ITER reactor, this knowledge will be gathered by a sophisticated neutron flux diagnostic system.
Space missions rely on cryogenic fluids—extremely cold liquids like liquid hydrogen and oxygen—for both propulsion and life support systems. These fuels must be kept at ultra-low cryogenic temperatures to remain in liquid form; however, solar heating and other sources of heat increase the rate of evaporation of the liquid and cause the pressure in the storage tank to increase. Current storage methods require venting the cryogenic propellant to space to control the pressure in fuel tanks.
Researchers have used the centuries-old idea of pinhole imaging to create a high-performance mid-infrared imaging system without lenses. The new camera can capture extremely clear pictures over a large range of distances and in low light, making it useful for situations that are challenging for traditional cameras.
Vibrations are everywhere—from the hum of machinery to the rumble of transport systems. Usually, these random motions are wasted and dissipated without producing any usable work.
The Great pyramid of Giza was considered a tomb, but many authors and researchers firmly agree that it was a structure that channeled, captured and encapsulated light—it was meant to be the Sunlight in Stone Ancient Egyptians built the pyramids using engineering techniques that are a wonder of the world Ancient Egyptians are believed to have built the Pyramids thousands of years ago as massive tombs for their dead Pharaohs. Until this day we still have no idea how the Pyramids were built, how the ancient Egyptians transported the massive blocks for quarries located up to 500 kilometers away, nor do we know how they managed to place the massive stones in such an intricate fashion, which eventually resulted in magnificent ancient structure such as the Great Pyramid of Giza. In the same way as the Incas have been credited with the prehistoric stone work in Peru, so were the ancient Egyptians credited for the pyramids of Giza. The only difference here is that the pyramids are conveniently labeled as “tombs” rather than temples.
Therefore, we have been told that the three pyramids of Giza, were constructed by three Pharaohs believed to date back to the third millennium BC – Khufu was usually known as Cheops, originally Khnum-Khufu, Khafra -also read as Khafre, Khefren and Chephren, and Menkaure. In this article, we take a look at the pyramid of Cheops. It is commonly known as the Great Pyramid and represents the last survivor of the Seven Wonders of the Ancient World. But did the Great Pyramid actually belong to Khufu , and if so, was it ever a tomb? Many authors and researchers disagree that the great Pyramid was erected by Khufu, while also disagreeing with the notion that the Great Pyramid was used as a tomb. The orthodox explanations behind the construction of the Egyptian pyramids, especially the one attributed to pharaoh Khufu have consistency whatsoever. In fact, later studies and research silenced by the most conservative and traditional archaeologists, come to surprising conclusions: the ancient Egyptians knew a technique–now forgotten–that allowed them to “create” artificial stones.
Stones that today are seen millimetrically integrated into what is considered their greatest ever architectural feat. For many, the matter is beyond doubt: Pharaoh Cheops reigned for 23 years, twenty of which he dedicated to the construction of the greatest monument that man has ever erected. This entire idea comes from what was told in The Nine Books of History written by Herodotus: “… As for the pyramid, twenty years were spent on construction…” But let me ask you something right there… Do you really believe that twenty years went by—7,000 years ago—as workers of the Copper Age raised with astonishing precision around two million six hundred thousand blocks of stone, each weighing 2 tons each (at least)? This means that each year, they had to place 130,000 blocks of stone, which in turn means they had to place 360 a day. If we make a rough calculation of the working day of ancient Egyptian labourers at that time, and say that it consisted of a 12-hour period, we get that for 20 years, without knowing the iron and the wheel, the architect of the Great Pyramid organized a work team that was capable of quarrying the massive stones, cutting them, and transporting them for up to hundreds of kilometers across the Nile, while somehow managing to lift these blocks up to a height of hundreds of meters, and place them into position with incredible precision, and ALL OF THAT in a record time of 120 seconds PER BLOCK. This is of course according to orthodox explanations, who basically say that ancient Egyptian workers so close to the Paleolithic, were capable of fitting for twenty years a block onto the Great Pyramid every two minutes. Does that make any sense? And while building the Great Pyramid in RECORD time, apparently they managed to incorporate countless mathematical formulas and places the Great Pyramid of Giza which such precision, that engineers, and architects which modern-day tools would have a hard time replicating their work.

Using radial velocity measurements, an international team of astronomers has identified a second planet orbiting a nearby M-dwarf star known as Gliese 536. The newfound alien world turns out to be at least a few times more massive than Earth. The findings are covered in the upcoming issue of Astronomy & Astrophysics and currently available on the arXiv preprint server.
