Jupiter’s New Size // NO Moon Impact // More Years for ISS
Why It Matters
These updates reshape scientific understanding, resolve key cosmological tensions, and secure the commercial and operational foundation for humanity’s next steps in space.
Key Takeaways
- •2024 YR4 asteroid will miss the Moon, no 2032 impact.
- •Jupiter’s polar radius 12 km smaller, making it flatter than thought.
- •LOFAR’s low‑frequency sky map catalogs 13.7 million radio sources.
- •Gravitational‑lens supernova and wave background offer new Hubble constant routes.
- •U.S. Senate extends ISS to 2032, pushes commercial station partnerships.
Summary
The weekly Space Bites covered five major developments: asteroid 2024 YR4 will safely fly past the Moon in 2032, new Juno‑based measurements show Jupiter is slightly smaller and markedly flatter, LOFAR completed an unprecedented low‑frequency radio map of 13.7 million objects, astronomers introduced two novel approaches to resolve the Hubble tension, and the U.S. Senate approved extending the ISS to 2032 while encouraging commercial station partners.
Detailed data: the asteroid will miss the Moon by about 20,000 km, confirming a 0% impact probability; Jupiter’s polar radius is now 66,842 km (12 km less) and equatorial radius 71,488 km (4 km less), yielding a flattening 20× Earth’s; LOFAR’s 52‑antenna array gathered 18.6 petabytes over 13,000 hours; the gravitational‑lens supernova produced five images for a more precise time‑delay measurement, and background gravitational‑wave “cosmic sirens” are projected to constrain H₀ within six years.
Notable quotes: researchers noted “Jupiter is 20 times flatter than Earth,” highlighting the planet’s unexpected shape; LOFAR team emphasized the map’s value for SETI searches; and cosmologists stressed that gravitational‑wave sirens could finally reconcile the divergent Hubble constant values.
Implications: confirming the asteroid’s harmless flyby eases public concern, while Jupiter’s revised dimensions refine interior models and mission planning. The LOFAR catalog opens new windows for multi‑wavelength astronomy and potential extraterrestrial signal detection. Independent Hubble measurements could resolve a central cosmology crisis, influencing dark‑energy theories. Extending the ISS and courting private stations ensures continuous low‑Earth‑orbit research and accelerates the transition to a commercial space‑infrastructure, supporting future lunar and deep‑space ambitions.
