Life in the clouds of Venus: The presence of phosphine on the planet has been confirmed
A year after discovering phosphine gas in the atmosphere of Venus, a signal that many believe may be a sign of microscopic life, the research team behind the discovery has re-examined the findings. And, they say, this analysis only confirms their original findings.
On Earth, most living things release carbon dioxide or oxygen into the atmosphere. But some species of organisms that live in extreme conditions, dubbed “extremophiles,” can emit phosphorus gas, known as phosphine.
In 2020, researchers examining data from a pair of large telescopes found distinctive signatures of this gas in the Venusian atmosphere, and in concentrations that indicate the presence of life spewing phosphine.
“The chemical phosphine (PH3) is considered a biomarker because it is difficult to create by the normal chemical processes believed to occur on or around a rocky planet such as Venus,” the NASA report explains.
The discovery sparked a wave of reactions, from outright elation over the discovery of signs of extraterrestrial life to doubts about whether the phosphine signal had been detected at all.
In an attempt to solve this problem, at least as far as possible before in situ measurements by future probes can answer the question once and for all, the research team, which initially got controversial results, took a fresh look at the data. And what they found seems to confirm their original conclusion.
“Re-analysis of inherited data collected by NASA’s Pioneer-Venus Neutral Gas Mass Spectrometer (LNMS) at 51.3 km shows the presence of PH3 in the clouds of Venus,” the researchers explain in a statement.
Moreover, they note that “PH3 (phosphine) is the only P-containing molecule that matches the data and is in gas form at 51.3 km above the level of Venus.
This is quite convincing, the researchers note, because “+P does not overlap with any other fragment of neutral gas mass expected from the atmosphere of Venus, which gives +P a unique and reliable detection.”
Feeling confident in their conclusion, the researchers confirmed the result, including ruling out a possible false signal from a naturally occurring process.
“It could be argued that there are very small amounts, such as phosphoric acid vapor, that could have fragmented into +P,” the researchers suggested, “but confirmatory acid fragmentation ions were not detected, and they should have been.”
In the end, the research team concluded, “We insist on the existence of phosphine in the atmosphere of Venus, while recognizing that the dispute may never be resolved until in situ measurements in the atmosphere of Venus are returned.”
In June 2021, NASA announced a pair of future missions to the fiery world, both of which will feature instruments capable of ending the phosphine controversy once and for all. The two missions, named DAVINCI+ (Exploring Noble Gases, Chemistry and Imaging in Venus’ Deep Atmosphere) and VERITAS (Exploring Venus’ Radiative Capability, Radar, InSAR, Topography and Spectroscopy), are part of NASA’s Discovery program.
“Using the advanced technology that NASA has developed and refined over many years of missions and technology programs, we are beginning a new decade of studying Venus to understand how an Earth-like planet can become a greenhouse,” NASA Assistant Administrator for Science Thomas Zurbuchen said in a statement about the two new missions. “Our goals are profound. It’s not just to understand planetary evolution and habitability in our own solar system, but to go beyond those limits to exoplanets, an exciting and evolving area of NASA research.”
The launch of both DAVINCI+ and VERITAS satellites is expected around the end of this decade, so it may be some time before that question is answered definitively.
However, given the detailed reanalysis of the original signal by a team of researchers, as well as attempts by these same researchers to respond directly to each of the previous criticisms of their original finding, the options seem to be increasingly narrowed toward the original finding being credible.

NASA Discovers Hyper-Speed Object That Could Break Free from the Milky Way
According to NASA, a rogue, hyper-speed object, which is over
27,306 times the size of Earth, is hurtling so fast through our galaxy
that it might break free of the Milky Way.
Scientists say they have determined that the mysterious object was
cruising at a breakneck one million miles per hour when they spotted it
more than 400 light years from Earth. One light-year is equal to six
trillion miles.
Could this latest find be connected to the fake alien invasion that has long been in the pipeline?
The Mail Online reorts: While experts have not determined what the newfound celestial body is, they speculated it is a ‘brown dwarf,’ a star which is larger than a planet but lacks the mass to sustain long-term nuclear fusion in its core like Earth’s sun.
If the object confirmed as a brown dwarf, it would be first-ever to
be documented in a chaotic, hyper-speed orbit capable of breaking free
from our home galaxy.
A coalition of citizen-scientists with NASA’s ‘Backyard Worlds: Planet 9’ projectwere the first to spot the celestial body, the US space agency confirmed this week.
‘I can’t describe the level of excitement,’ German citizen-scientist Martin Kabatnik, a long-time member of NASA’s Backyard Worlds program, said in statement.
‘When I first saw how fast it was moving,’ the Nuremberg-based
researcher confessed, ‘I was convinced it must have been reported
already.’
Backyard Worlds citizen-scientists Martin Kabatnik, Thomas P. Bickle
and Dan Caselden were the first to spot this million mph object a few
years ago, earning the hyper-speed object the catalogued name CWISE
J124909.08+362116.0.
According to astronomer Dr Kyle Kremer,
who has collaborated with them on better understanding the object,
several astrophysics theories could explain how the object, CWISE J1249
for short, could have gotten to its incredible speed.
In one theory, CWISE J1249 rocketed out of a two star or binary star
system after its ‘white dwarf’ sister star died off — collapsing in an
explosive runaway nuclear fusion reaction called a supernova.
Another viable theory has it that CWISE J1249 originated inside a
tight cluster of starts called a ‘globular cluster’ where it was flung
free via the pull of a black hole.
‘When a star encounters a black hole binary,’ Dr Kremer said in a
NASA statement on the discovery, ‘the complex dynamics of this
three-body interaction can toss that star right out of the globular
cluster.’

Polish astronaut prepares for 2025 flight to ISS

Sławosz Uznański will be the second Pole in space and the first to fly to the International Space Station (ISS).
Uznański revealed that his mission to the ISS is planned for 2025 and will last about two weeks. He will launch from Cape Canaveral on a rocket provided by SpaceX. This journey not only represents a significant milestone for Uznański but also for Polish space exploration.
Last year, Uznański was officially selected for this mission, after which he commenced his training at the European Space Agency’s facility in Cologne, Germany. Initially planned for 2024, the mission faced delays, but new details have recently emerged on Uznański’s social media profiles.
During his two-week stay on the ISS, he will focus on Polish scientific projects and technology tests, including artificial intelligence applications in space and studies on the effects of microgravity on the human immune system.
The European Space Agency (ESA) and the Polish Space Agency (POLSA) received numerous project proposals for Uznański’s mission. Due to limited space, only seven were selected, highlighting the extensive interest and potential impact of this mission.
Uznański will travel to the ISS in SpaceX’s Crew Dragon capsule, a vehicle regularly used by NASA for transporting astronauts. The Crew Dragon will be mounted atop a Falcon 9 rocket, with the launch also set to take place at Cape Canaveral. While the exact launch date is yet to be confirmed, preparations are in full swing.
In a move to further his training, Uznański has relocated to Houston, Texas. Starting Monday, he will begin a new training phase at Axiom Space, a partner in the mission, followed by sessions at NASA and SpaceX facilities. This mission not only propels Uznański into space but also significantly advances Poland’s stature in the global aerospace sector.
