Doomed Soviet spacecraft Kosmos 482 could hit Earth tonight. Here's when.
- The failed Soviet spacecraft Kosmos 482 is expected to reenter Earth's atmosphere this weekend, possibly crashing as early as tonight.
- Predictions from the European Space Agency suggest a reentry time around 2:26 a.m. EDT on Saturday, with a window between 10 p.m. EDT Friday and 7 a.m. EDT Saturday.
- Kayhan Space predicts a narrower window for reentry at 2:28 a.m. ET on May 10, plus or minus 2.4 hours.
- The uncertain atmospheric density in lower altitudes poses challenges for precise predictions.
- The 1-meter-wide Kosmos 482 could land anywhere between 52 degrees north and 52 degrees south, with high likelihood of ocean landing.
- The prospect of the spacecraft hitting a person is minimal, typical of falling space debris scenarios.
- Kosmos 482 was part of the Soviet Venera mission to Venus in 1972 but got stuck in Earth's orbit due to a rocket malfunction.
- With over 1.2 million space debris pieces in orbit, reentries and collisions are increasing, emphasizing the need for responsible end-of-life plans for satellites.

Part of Soviet-era spacecraft to crash to Earth this weekend
- Part of a Soviet spacecraft, Kosmos 482, is expected to crash back down to Earth this weekend, uncertain of the landing location.
- Launched in 1972, the spacecraft was intended for Venus but failed to escape low Earth orbit and broke into four pieces.
- The robust design of the spacecraft, meant to withstand Venus's extreme conditions, is likely to survive re-entry into Earth's atmosphere.
- The landing probe could crash between latitudes of 52 degrees north and 52 degrees south, with expected re-entry from 9 to 10 May.

NASA Study Reveals Venus Crust Surprise
- New NASA-funded research reveals surprising findings about the crust on Venus, Earth's hotter twin.
- Contrary to expectations, Venus' crust does not grow thicker over time but experiences a crust metamorphism process based on rock density and melting cycles.
- Venus has a one-piece crust with no plate tectonics like on Earth, making its 25-40 miles thick crust subject to metamorphism.
- The research suggests that Venus' crust undergoes processes like breaking off, melting, and driving volcanic activity, offering new insights into the geological evolution of the planet.

Hubble observes a rogue black hole devouring a star
- Astronomers using the Hubble Space Telescope have observed a black hole devouring a star, creating a tidal disruption event (TDE) named AT2024tvd.
- The black hole, located 2,600 light years away, was a wandering rogue unlike most supermassive black holes usually found in the center of galaxies.
- The researchers used Hubble, NASA’s Chandra X-Ray Observatory, and the NRAO Very Large Array telescope to observe the TDE and study the black hole's behavior.
- The galaxy where this event occurred contains two supermassive black holes, suggesting a previous merger of smaller galaxies, and theorizing a potential future merger of the two black holes.

Conclave: What’s in that black or white smoke?
- White smoke from the Sistine Chapel signifies the election of a new Pope during a papal conclave.
- The tradition of using smoke signals originated from burning ballot papers for secrecy in the 15th century.
- Black smoke indicates no consensus among cardinals, while white smoke confirms the selection of a new Pope.
- Initially, the smoke was not intended as public signaling, but observers interpreted it as such over time.
- Earlier methods involved burning damp straw and tar, leading to confusion between black and white smoke colors.
- The current formula for generating black smoke at the conclave includes potassium perchlorate and anthracene.
- White smoke is produced using potassium chlorate, lactose, and pine rosin for a cleaner combustion process.
- Modern chemistry has refined the smoke production to ensure clear distinctions between black and white smoke signals.
- The evolution of the smoke signaling system at the conclave highlights its transformation into a precise communication tool.
- The practice of generating white or black smoke has become a distinctive and unmistakable feature during papal elections.

Our constant human presence in space nears 25 years
- In 2025, we mark 25 years of humans continuously inhabiting space since the first crew launched to the International Space Station on October 31, 2000.
- Anyone born after October 30, 2000, has never known a day without a human presence in space, according to the NASA History Office.
- The space race between the U.S. and Soviet Union led to milestones like Yuri Gagarin's orbit in 1961 and Valentina Tereshkova becoming the first woman in space in 1963.
- Neil Armstrong's historic moonwalk on July 20, 1969, marked the first time humans set foot on the moon, followed by 11 more lunar astronauts through 1972.
- Before the ISS, the Mir space station operated from 1986 to 2001, contributing to our continuous human presence in space.
- China's space station Tiangong, launched in 2021, joins the ISS in orbiting Earth, extending our human presence in space.
- The ISS's lifetime is limited, set to be deorbited in 2031, but plans for future space stations like lunar Gateway and Mars missions ensure our sustained presence in space.
- Humans have been consistently in space for 25 years, and with ongoing space missions, our presence in space is expected to continue.
- NASA plans to bring down the ISS in 2031, possibly guiding it to a watery demise in the Pacific Ocean near Point Nemo.
- Despite the ISS's end, the Tiangong space station and upcoming projects like lunar Gateway and Mars missions ensure our enduring human presence in space.

Hubble Comes Face-to-Face with Spiral’s Arms
- The Hubble Space Telescope recently captured an image of the spiral galaxy NGC 3596, located 90 million light-years away in the constellation Leo.
- NGC 3596 appears almost face-on from Earth, showcasing its neatly wound spiral arms with concentrations of stars, gas, and dust indicating active star formation.
- The formation of spiral arms in galaxies has puzzled astronomers, with varying structures and the 'winding problem' historically challenging to explain.
- Recent research suggests that spiral arms represent patterns of high-density and low-density areas rather than physical structures, with materials moving through them akin to cars in a traffic jam.
