  Today (Aug. 25), the sun unleashed a powerful M6.9 solar flare from a restless Earth-facing sunspot, hurling a coronal mass ejection (CME) into space — and Earth could potentially be in the firing line. The M6.98 solar flare erupted from the active sunspot region 4513 and peaked at 6 a.m. EDT (1000 GMT), according to SpaceWeatherLive. 4513 has been particularly active over the last 24 hours, firing off a barrage of solar flares including five powerful M-class eruptions. Solar flares are ra

  On Aug. 25, 1997, NASA launched the Advanced Composition Explorer, or ACE satellite to study energetic particles traveling through space.It lifted off from Kennedy Space Center in Florida on a Delta II rocket and spent the next three and a half months making its way to its orbital post near the L1 Lagrangian point, a point of gravitational equilibrium between Earth and the sun. There, the spacecraft is monitoring the stream of accelerated particles coming from the sun known as the solar wind.ACE

• NASA satellites ace world's 1st 'lost-in-space' GPS-free navigation experiment

  25-08-2026 14:00 via space.com
  
  No GPS available in space? A satellite experiment may have a solution for that.NASA's Starling mission — made up of a swarm of four cubesats in low Earth orbit (LEO) — is testing out navigation by using other satellites as moving landmarks. The hope is that this tech will allow future missions to navigate if GPS is not available.The three-year-old tech demo will be extended beyond its previous expiration date this year until at least 2028, NASA announced on Monday (Aug. 17). The aim

  25-08-2026 09:00 via space.com
  
  A dramatic partial lunar eclipse will occur on Aug. 27-28, with almost the entire moon slipping into Earth's shadow. At its peak, at 12:12 a.m. EDT (0412 GMT) on Aug. 28, 96.2% of the lunar surface will be covered by Earth's dark umbral shadow, leaving only a slender portion of the moon directly illuminated by the sun. The rest of the lunar surface may take on an eerie reddish-orange hue, creating an impressive 'almost blood moon'. The eclipse will be visible from North and South America, Europe
