• The moon will hide Jupiter in broad daylight on Sept.8 — here's how to see it

  07-09-2026 18:00 via space.com
  
  On Tuesday (Sept. 8), skywatchers can first catch a striking predawn pairing of the crescent moon and Jupiter, then — where conditions and location allow — attempt the much harder daytime occultation, when the moon hides the planet from view.Before sunrise: Find the moon and JupiterSet your alarm for 5 a.m. local time on Tuesday and look low toward the east-northeast sky. Check in advance for tall obstructions that could block your view of this delicate predawn tableau. A slender wan

• On this day in space! Sept. 10, 2011: NASA launches GRAIL probes to the moon to map lumpy lunar gravity

  10-09-2026 20:01 via space.com
  
  On Sept. 10, 2011, NASA's GRAIL spacecraft launched on a mission to the moon! GRAIL, which stands for Gravity Recovery and Interior Laboratory, was sent to the moon to map its gravitational fields. Scientists could study the moon's interior structure by looking at maps of the moon's gravity. Asteroid impacts from billions of years ago left dense pockets of material under the lunar surface, which can exert extra gravitational pull on spacecraft orbiting the moon. So by measuring that gravitationa

  LINK, the satellite sent to boost the orbit of NASA's Swift Observatory, may have had to give up on its mission, but LINK's manufacturer and operator Katalyst Space hasn't completely abandoned the spacecraft to its cosmic demise.NASA called off LINK's mission to rendezvous with its Neil Gehrels Swift Observatory when the specialized probe encountered a thruster control issue. LINK was delivered to orbit on July 3, aboard an air-launched Northrop Grumman Pegasus XL rocket, but began to spin uncon

• Scientists study 3,000 supernovas and discover that dark energy may be evolving

  10-09-2026 18:00 via space.com
  
  A catalog of almost 3,000 white dwarfs that exploded as type Ia supernovas after overfeeding on companion stars indicates that dark energy, the mysterious force accelerating the expansion of the universe, is changing over time.The discovery, in conjunction with data from the Dark Energy Survey (DES), backs results revealed from the Dark Energy Spectroscopic Instrument (DESI) published in 2024 that suggested dark energy's influence is weakening. That means that the team's research doesn't just in

  During the recent press rounds for Apple TV's Ryan Reynolds/Kenneth Branagh vehicle "Mayday", writer/director duo Jonathan Goldstein and John Francis Daley talked about their plans for the next "Star Trek" movie. As well as confirming their story will feature an all-new crew, they mentioned that the in-development project will be inspired by a pair of hit films from the '90s and '00s, both of which — coincidentally — feature Denzel Washington operating at very different ends of the m

• Mercury is shrinking faster than we thought. What's going on inside of it?

  10-09-2026 17:00 via space.com
  
  Wrinkles on the surface of Mercury have revealed that the closest planet to the sun is shrinking faster than scientists thought.New research suggests that Mercury is shrinking between 10% and 30% faster than had been previously estimated. The team behind this research calculated that the planet has lost nearly 12 miles (19 kilometers) of its total diameter since it formed. The researchers think that the extremity of this shrinking has gone unnoticed previously because bombardment from space rock

• Strange 'fast radio bursts' across the universe could help solve major cosmic mysteries: 'It's only the beginning'

  10-09-2026 12:00 via space.com
  
  Though their origins may be shrouded in mystery, fast radio bursts (FRBs) could be used to probe some of the universe's biggest puzzles. This includes probing the nature of dark matter, the invisible sort of matter that somehow dominates the universe, and dark energy, the mysterious force causing the expansion of our universe to accelerate. They could even shed light on the mysteries of neutrinos, or "ghost particles." Let's dive into how.FRBs are brief but intense blasts of radio waves currentl

  A "forbidden" merger between two massive black holes may not have been quite as impossible as previously thought. That's according to new research that suggests the black holes involved were smaller than expected.On Nov. 23, 2023, the gravitational wave detector LIGO (Laser Interferometer Gravitational-Wave Observatory) detected tiny ripples in spacetime caused by the merger of two black holes.

• Astronomers discover two stars that joined together to form a binary system just 60 years ago

  09-09-2026 21:00 via space.com
  
  Using the ALMA (Atacama Large Millimeter/submillimeter Array) radio telescope, astronomers have watched as two stars come together to form a massive stellar binary. The observations revealed that these stars didn't form from the same collapsing cloud of gas and dust, as most binary stars are assumed to form, but instead came together later in their infancy. Here on Earth, we are slightly prejudiced by our single sun to view stars as somewhat solitary bodies. However, around half of sun-sized sta

  A brand new observatory began its tenure on Aug. 30 — it's called the Nancy Grace Roman Space Telescope, and it's equipped with a high-tech tool that can directly photograph planets beyond our solar system.The tool is called a coronagraph; in simple terms, a coronagraph is a device that can be affixed to a telescope and block out the light of a star the telescope is looking at to study features around that star. Without such a device, starlight can be so overpowering that it outshines deta

  Global warming will soon cross a critical threshold, surpassing a dangerous limit set years ago, the United Nations Environment Programme (UNEP) has found. But experts say it's still possible to cool things back down, emphasizing that the stakes are too high to stop trying. In 2015, 196 nations and territories signed the Paris Agreement, pledging to restrict the average rise of global temperatures to below 2 degrees Celsius (3.6 degrees Fahrenheit) above pre-industrial levels.

• A photon from the biggest cosmic explosion since the Big Bang appears to have defied Einstein. Scientists may finally know how

  A photon, or particle of light, from the biggest cosmic explosion since the Big Bang, nicknamed "the BOAT" (for the brightest of all time), should not have reached Earth. That is, unless it defied rules defined by Einstein. Now scientists may know how it did this, with new research suggesting how the high-energy photon may have survived a journey of more than two billion light-years without being absorbed.The BOAT, a gamma-ray burst officially designated GRB 221009A, was first detected on Oct. 9

  Starting today (Sept. 9), skywatchers in the Northern Hemisphere have a chance to spot one of the night sky's more elusive sights: the zodiacal light.Zodiacal light is a faint, pyramid-shaped glow rising in the east before morning twilight. It is caused by sunlight reflecting off interplanetary dust.The phenomenon is sometimes nicknamed the "false dawn" because its soft glow can be mistaken for the signs of morning twilight. Unlike dawn, however, the zodiacal light appears as a distinct cone or

  Scientists may finally know why Venus, Earth's twin, lacks a moon, finding that the hottest planet in the solar system may have consumed its own natural satellite. Venus is often referred to as Earth's twin due to its size, mass, rocky composition, and distance from the sun, but there are some glaring differences between the two planets. Aside from Venus' blisteringly hot temperature, which could melt lead, incredible surface pressure, violent high-speed winds, and clouds of sulfuric acid, one o

  On Sept. 8, 2004, NASA's Genesis spacecraft crash-landed in Utah after its parachutes failed to deploy. Genesis was NASA's first sample-return mission since the Apollo program, and the first attempt ever to bring back samples from someplace farther than the moon. The spacecraft picked up solar wind particles while orbiting the L1 Lagrange point, which is about 1 million miles from Earth. L1 is a "sweet spot" between the Earth and the sun, where the gravitational pull from both objects balances o
