This asteroid will skim by Earth and be visible with the naked eye. And scientists have calculated whether it will hit us | BBC Sky at Night Magazine

  • Apophis will pass Earth at a distance of about 32,000 kilometers during its 2029 approach, a proximity that enables highly detailed observations from ground-based facilities under dark skies.
  • The new reference reinforces that NASA sees no imminent risk from Apophis for at least a century, despite its dramatic size and close pass.
  • The encounter, viewed as a landmark science event, will drive global interest in studying how Earth's gravity subtly warps and alters near-Earth objects like Apophis.
  • Observatories around the Eastern Hemisphere may offer naked-eye viewing of Apophis depending on weather, timing, and parallax, highlighting accessibility for amateur skywatchers.
  • Apophis is a sizable body, roughly hundreds of meters across, underscoring why its close approach has drawn sustained scientific and public interest since its discovery.
  • Analyses from radar and telescope data over the years have steadily reduced the perceived collision risk, aligning with the broader consensus that long-term danger is minimal.
  • Post-2029, Apophis will reappear in 2036 but at a much greater distance, reducing the likelihood of close approaches in the near term.
  • The event is framed as a rare opportunity to advance understanding of Apophis and similar near-Earth objects rather than a danger to humanity.
  • The 2029 flyby is anticipated to catalyze collaboration between ground observations and upcoming missions to probe gravity effects and surface changes on Apophis.
  • Caliber.az’s coverage notes that Apophis’s close pass is a once-in-multiple-thousand-year event in terms of its combination of size, proximity, and observational capability.

Apollo v Artemis: How the Earth changed in 58 years

  • NASA’s Artemis II photo, Earthset, shows Earth from the Moon during a seven-hour flyby, highlighting ongoing planetary change.
  • Earthrise 1968 and Earthset 2026 illustrate climate-linked surface changes seen from space, including ice loss around Antarctica.
  • Experts point to Antarctic ice loss and a retreating cryosphere as visible changes since 1968.
  • Earthset reveals daytime cloud cover and night-side darkness, showing how oceans and land reflect change.
  • NASA officials emphasize the human element in Earth imagery, arguing photographs carry emotional framing.
  • The article links Earthrise to the creation of Earth Day and environmental advocacy.
  • Experts attribute much of the observed change to human activities, with limitations from cloud cover in photos.
  • The piece notes the expansion of cities and bright agricultural lands visible from space.
  • The Earthrise/Earthset comparison highlights how perception shapes our understanding of climate data.
  • BBC researchers stress the enduring impact of space imagery on public awareness of the Earth's changes.

Canadian astronaut’s bon mots help heal wounds from French language row

  • During Artemis II, Jeremy Hansen greeted the world in French from space, underscoring bilingual representation.
  • The moment followed a wider controversy over Air Canada’s handling of French, which sparked political backlash in Canada.
  • Officials and commentators praised Hansen's effort as meaningful, even if not perfect, strengthening cultural ties.
  • The Artemis II mission was framed in the Guardian piece as a moment of cultural significance tied to Canada’s language politics.
  • Jeremy Hansen has a long history with bilingual outreach and links to Indigenous partnerships in Canada.
  • The article ties Hansen’s language choice to a broader view of space as a space for shared human identity.
  • Artemis II’s greeting occurred as part of a broader celebration of Canada’s cultural and linguistic diversity.
  • Hansen’s mission patch was designed by Anishinaabe artist Henry Guimond and features elements linked to Indigenous symbolism.
  • The Guardian notes Hansen’s remarks about space communicating shared human experience and learning from elders.
  • The piece situates language learning as a broader cultural and political issue in Canada.
