What ‘fluffy clouds’ can teach scientists about how stars are born
- Stars are born in molecular clouds, with elongated structures influencing star formation.
- A study in The Astrophysical Journal examines star formation in the Small Magellanic Cloud (SMC), resembling early universe conditions.
- Findings show 60% of SMC molecular clouds are filamentary, while 40% are fluffy, impacting star formation.
- Temperature differences suggest clouds start hot and cool over time, affecting structure.
- Filamentary clouds likely produce multiple stars, while fluffy clouds may struggle to form low-mass stars.
- Heavy elements influence cloud structure, potentially impacting star formation outcomes.
- Study challenges assumptions about star formation in low-metallicity environments like the early universe.
- Observations emphasize the role of heavy elements in shaping molecular cloud structures and star formation.
- Comparison with more metal-rich environments like the Milky Way is recommended for further insights.
- Studying nearby galaxies such as the SMC provides valuable insights into early star formation processes.

Thousands of new black holes just found!
- Astronomers have discovered thousands of new black holes using the Dark Energy Spectroscopic Instrument (DESI) at Kitt Peak in Arizona.
- The discoveries include more than 300 intermediate-mass black hole candidates and around 2,500 dwarf galaxies with actively feeding black holes at their centers.
- The census of black holes in both categories has tripled due to these findings.
- The DESI mission aims to survey millions of galaxies and has already identified new black hole candidates in distant galaxies using only a fraction of the data.
- Co-author Rahma Alfarsy expressed excitement about the potential discoveries from DESI's data.
- The researchers published their findings in The Astrophysical Journal on February 19, 2025.
- The team led by Ragadeepika Pucha looked at the spectra of 410,000 galaxies, highlighting the importance of active galactic nuclei in dwarf galaxies for finding black holes.
- 300 intermediate-mass black hole candidates were identified, potentially bridging the gap between supermassive and stellar-mass black holes.
- The research poses questions about the formation mechanisms of black holes and their relation to the types of galaxies they inhabit.
- The discoveries are crucial for enhancing our understanding of black holes and their impact on galaxy evolution.

Asteroid YR4 impact odds plummet as NASA changes threat level of 'city-killer'
- NASA has downgraded the threat level of potential city-killer asteroid 2024 YR4.
- The odds of the asteroid hitting the moon are now higher than it hitting the Earth.
- The impact probability for the asteroid has decreased to 1 in 360, or 0.28%.
- This reduction in odds has caused the threat level to drop from level 3 to level 1.

Address science misinformation by building community
- Scientists are increasingly discussing ways to address science misinformation, such as falsehoods about vaccines and climate change.
- Combatting misinformation involves more than just sharing facts, as some information can feel threatening to individuals.
- Changing minds about misinformation requires working within social networks and communities to influence beliefs and social norms.
- Human behavior shows that people are more likely to adopt beliefs held by their trusted social circles, even if evidence contradicts them.
- Leveraging community networks and building trust within social groups can help correct misinformation effectively.
- India successfully eradicated polio by engaging with vaccine-resistant communities through personal interactions and building trust.
- Deep canvassing, a method focusing on engaging with different viewpoints, has shown success in promoting conversations on controversial science topics.
- Examples like Neighbors United in Canada demonstrate how deep canvassing can lead to shifts in community views and actions towards climate change.
- Creating support for science-based attitudes and behaviors involves meaningful dialogue and interactions between skeptics and scientific messengers.
- To combat science misinformation effectively, it is crucial to engage in personal conversations, share stories, and work within social networks.

‘What a lie’: Danish astronaut responds to Musk claim that Biden abandoned ISS pair on purpose
- Danish astronaut, Andreas “Andy” Mogensen, has responded to Elon Musk's claim that former president Joe Biden intentionally abandoned two American astronauts aboard the International Space Station (ISS).
- Musk accused Mogensen of lying and called him 'fully retarded'. He claimed that SpaceX could have brought the astronauts back earlier and had made an offer to the Biden administration.
- The two astronauts, Butch Wilmore and Suni Williams, were initially stranded on the ISS after experiencing thruster problems during a test mission onboard Boeing Starliner. They are set to return on the SpaceX Crew-9 mission's spaceship.
- Mogensen clarified that the return of the astronauts on the Dragon capsule, which has been on the ISS since September, has been the plan since last year.
