Gigantic ‘Bubble of Galaxies’ found stretching across billions of light years
- Scientists studying galaxy movements have discovered signs that our cosmic neighborhood may be part of a much larger system than previously believed.
- Analysis of over 56,000 galaxies by the Cosmicflows group revealed evidence of a galactic basin, Laniākea, possibly ten times larger than its known size.
- New data indicates a 60% chance that Laniākea extends towards the Shapley concentration, a region dense with mass and gravitational force.
- The discovery challenges current views on cosmic structures and suggests that the universe's architecture may need revision to show larger interconnected basins.
- The study implies that cosmic structures began growing more extensively than previously thought and questions the completeness of current cosmic surveys.
- Researcher Ehsan Kourkchi highlighted the challenges posed by the immense cosmic basins and the limitations of current survey tools.
- By analyzing the gravitational effects on galaxy movements, researchers can map the flow of galaxies within superclusters in the local universe.
- The ongoing research aims to understand the universe's interconnected cosmic system and our place within it, potentially linking our galaxy to grander structures.
- The study involves international astronomers like R. Brent Tully, Aurelien Valade, Noam Libeskind, and others, emphasizing the collaborative nature of astronomical research.
- The discovery challenges existing cosmic models, highlighting the vastness of the universe and continuing efforts to expand our knowledge of cosmic evolution.

Yankees and Torpedo Bats: Why’s Everyone Freaking Out Over a League-Wide Party?
- The New York Yankees have been hitting home runs at an impressive rate with their so-called 'Torpedo bats'.
- However, the Yankees are not the only players in MLB using these bats; other players from different teams like Orioles, Blue Jays, Twins, Rays, and Cubs have also been seen using them.
- The outrage towards the Yankees is considered hypocritical as the Torpedo bats were not invented by the team; they were developed by Aaron Leanhardt, an MIT physicist turned baseball guru.
- Leanhardt's concept behind the Torpedo bats is to optimize the bat's mass where hitters make contact with the ball, resulting in more effective hits.

James Webb telescope takes emergency look at 'city-killer' asteroid 2024 YR4 ahead of close encounter in 2032
- The James Webb Space Telescope (JWST) observed asteroid 2024 YR4, a 'city-killer' asteroid approaching Earth and the moon in 2032.
- JWST's observation revealed that the asteroid may be larger and rockier than previously thought, but it poses no threat to Earth in 2032.
- There is a 2% chance that asteroid 2024 YR4 could collide with the moon in 2032, based on JWST data.
- Astronomers discovered asteroid 2024 YR4 in December 2024, estimating its size to be about 180 feet in diameter.
- The asteroid's trajectory crosses Earth's path, potentially endangering the planet if a collision were to occur.
- JWST's infrared sensors were crucial in studying the asteroid's size and composition, offering insights not available through ground-based telescopes.
- Despite some uncertainties, NASA confirmed a 0% chance of Earth impact by asteroid 2024 YR4 in 2032.
- The upcoming second round of JWST observations in May will provide further details on the asteroid's trajectory and likelihood of hitting the moon.
- While a lunar impact by the asteroid may occur in 2032, it does not pose a threat to Earth and could offer a unique research opportunity.
- Scientists are hopeful for a moon impact as it would allow studying the formation of a lunar crater by a known asteroid for the first time.

The Enigma of Black Holes: Cosmic Monsters That Bend Reality
- The information paradox surrounding black holes remains one of the greatest unsolved mysteries in physics, challenging our understanding of the universe.
- Approaching a black hole leads to spaghettification, where intense gravitational forces stretch an object into a thin, noodle-like strand, eventually tearing it apart.
- Black holes can significantly alter the perception of time, causing seconds for an observer to equate to millions of years for someone far away.
- Black holes have been theorized to potentially serve as cosmic weapons or gateways to other parts of the universe or parallel universes.

Powerful X-class solar flare caught on camera erupting from sun's surface
- On March 28, an X1.1-class solar flare erupted from a sunspot named AR4046 on the sun's surface, causing a radio blackout across two continents.
- This powerful solar flare, captured by the GOES-16 satellite, marked the first X-class flare released by the sun since early February.
- Solar flares are intense bursts of electromagnetic radiation classified on a scale of A, B, C, M, and X, with X-class flares being the most powerful.
- The flare triggered a radio blackout by ionizing Earth's upper atmosphere, disrupting high-frequency radio communications on the sunlit side.
- CMEs, such as the one following the flare, can cause geomagnetic storms and disturbances to satellites and power grids if they collide with Earth.
- While the CME from the March 28 solar flare is not expected to hit Earth, a new sunspot AR4048 is turning towards Earth and could release powerful flares.
- NOAA's Space Weather Prediction Center shared a video showing the solar flare and CME, emphasizing the potential impacts on communication and technology.
- Solar astrophysicists warn of the likelihood of further strong solar activity as the flare source region rotates to face Earth in the coming days.
- The article highlights the dangers of solar flares and CMEs in disrupting technology and communication systems on Earth.
- Experts note the importance of monitoring and preparing for potential impacts of solar eruptions to mitigate disruptions and ensure safety.

Why is the Far Side of the Moon Hidden?
- The Far Side of the Moon is always hidden from Earth due to a combination of the Moon's rotation and its orbital period.
- The Moon takes about 27 days to complete one rotation on its axis and around the Earth.
- This synchronous rotation means that the same side of the Moon is always facing Earth.
- It is a natural phenomenon and not related to any hidden secrets or conspiracies.
