A scorching hot world where metal clouds rain drops of titanium is the most reflective planet ever observed outside of our Solar System, astronomers said on Monday.

This strange world, which is more than 260 light years from Earth, reflects 80 percent of the light from its host star, according to new observations from Europe’s exoplanet-probing Cheops space telescope.

That makes it the first exoplanet comparably shiny as Venus, which is the brightest object in our night sky other than the Moon.

First discovered in 2020, the Neptune-sized planet called LTT9779b orbits its star in just 19 hours.

Because it is so close, the side of the planet facing its star is a sizzling 2,000 degrees Celsius, which is considered far too hot for clouds to form.

Yet LTT9779b seems to have them.

“It was really a puzzle,” said Vivien Parmentier, a researcher at France’s Cote d’Azur Observatory and co-author of a new study in the journal Astronomy and Astrophysics.

The researchers then “realised we should think about this cloud formation in the same way as condensation forming in a bathroom after a hot shower,” he said in a statement.

Like running hot water steams up a bathroom, a scorching stream of metal and silicate — the stuff of which glass is made — oversaturated LTT9779b’s atmosphere until metallic clouds formed, he said.

Surviving ‘Neptune desert’

The planet, which is around five times the size of Earth, is an outlier in other ways.

The only exoplanets previously found that orbit their stars in less than 24 hours are either gas giants 10 times bigger than Earth — or rocky planets half its size.

But LTT9779b lives in a region called the “Neptune desert”, where planets its size are not supposed to be found.

“It’s a planet that shouldn’t exist,” Parmentier said.

“We expect planets like this to have their atmosphere blown away by their star, leaving behind bare rock.”

The planet’s metallic clouds “act like a mirror,” reflecting away light and preventing the atmosphere from being blown away, according to the European Space Agency’s Cheops project scientist Maximilian Guenther.

“It’s a bit like a shield, like in those old Star Trek films where they have shields around their ships,” he told AFP.

The research marks “a big milestone” because it shows how a Neptune-sized planet could survive in the Neptune desert, he added.

The European Space Agency’s Cheops space telescope was launched into Earth’s orbit in 2019 on a mission to investigate planets discovered outside our Solar System.

It measured the reflectiveness of LTT9779b by comparing the light before and after the exoplanet disappeared behind its star.

2,300-Year-Old Dwarf Statuette from Alexandria Reveals Ptolemaic Art Insights

A 2,300-year-old marble statuette discovered in Alexandria, Egypt, has offered new insights into how dwarves were perceived during the Ptolemaic period (332–150 B.C.). Depicting a muscular, nude dwarf in motion, the 4-inch sculpture reflects a combination of Egyptian and Greek artistic traditions. Despite missing its arms, legs, and part of the head, the craftsmanship of the piece indicates a highly skilled rendering of human anatomy. It is currently housed at the Metropolitan Museum of Art in New York City.

Depictions of Dwarves in Ptolemaic Art

According to information from the Metropolitan Museum of Art, as reported by Live Science, the statuette incorporates elements from Greek art, such as classical nudity and Hellenistic realism, blended with Egyptian cultural aesthetics. This synthesis points to the cultural exchange that characterised the Ptolemaic dynasty, a period when Egypt was ruled by Ptolemy I Soter, a general of Alexander the Great. The depiction of a dwarf engaged in dance suggests a significant societal role, unlike the exaggerated caricatures of dwarves often seen in Greek art.

Egyptian Perspectives on Dwarves

Historical records indicate that dwarves were highly regarded in ancient Egypt, often serving in the households of nobles and pharaohs. Their association with the god Bes, who was depicted as a short and muscular protector of families and women in childbirth, contributed to their societal acceptance. Bes, known as a dancer and tambourine player, symbolises strength and guardianship in Egyptian mythology. The statuette’s design, which likely depicted the dwarf with a percussion instrument, aligns with this cultural significance.

A Glimpse into Cultural Integration

The artifact demonstrates the integration of different human forms into Egyptian society during the Ptolemaic era. The Met has emphasised that such depictions reflect a broader tradition of valuing diverse body types, setting the Egyptian approach apart from other ancient civilisations. This statuette, though small in size, offers a profound understanding of cultural dynamics during a transformative period in history.

Lunar Temperature Fluctuations: Understanding the Moon’s Extreme Conditions

Lunar Temperature Fluctuations: Understanding the Moon's Extreme Conditions

The surface temperature of the moon experiences extreme variations, making it one of the harshest environments in the solar system. During lunar daylight, temperatures can soar to over 100 degrees Celsius, while in darkness, they can plummet to minus 100 degrees Celsius. These fluctuations are caused by the absence of an atmosphere, which on Earth moderates temperature extremes. Instead, the moon’s surface directly absorbs and radiates heat depending on exposure to sunlight.

Lunar Temperature Variations Explained

According to data provided by NASA and analysed by experts, such as John Monnier, a professor of astronomy at the University of Michigan, the moon’s soil, or regolith, significantly influences these temperature shifts. Regolith is a poor conductor of heat, causing rapid temperature changes on the surface while insulating the subsurface. As reported by Live Science, during Apollo missions, measurements indicated that temperatures beneath the surface were warmer by 40 to 45 kelvins compared to the lunar exterior.

Further research using NASA’s Lunar Reconnaissance Orbiter (LRO), launched in 2009, revealed localised thermal anomalies. Findings in 2022 demonstrated that shaded areas within certain lunar pits maintained a consistent temperature of 17 degrees Celsius. These regions are considered promising for future human habitation.

The Moon’s Poles and Extreme Conditions

The lunar poles present unique thermal environments due to the sun’s low angle. Permanently shadowed craters, particularly at the south pole, may host temperatures as low as minus 248.15 degrees Celsius. These craters are shielded not only from direct sunlight but also from secondary heat sources, such as reflected solar radiation. Such locations could hold trapped ice particles, potentially vital for sustaining future lunar exploration missions.

Understanding the moon’s thermal dynamics is essential for designing equipment capable of withstanding its conditions and planning potential settlements. Scientists and engineers continue to study these extremes to ensure that future missions can navigate and thrive in the lunar environment.
