Right before Rocket Lab’s 53rd Electron rocket lifted off from its Launch Complex-1 in Mahia, New Zealand, the vehicle experienced a T-0 abort. The engines began firing as expected at T-2 seconds, but the vehicle remained on the pad. Image: Rocket Lab via launch livestream
Update Sept. 18, 9:47 p.m. EDT: Rocket Lab noted the scrub was due to “a ground systems sensor trigger.”
A low-density, weak-gravity region has been found below Olympus Mons and the Tharsis volcanoes, while Mars' northern hemisphere is littered with puzzling high-gravity structures beneath the surface.
Eleven objects found at the extremities of the solar system could mark the location of a 'Kuiper Belt 2.'
The secrets of dark matter might be hiding in the immense cosmic crashes that are colliding galaxy clusters.
If you are going to look for intelligent life beyond Earth, there are few better candidates than the TRAPPIST-1 star system. It isn’t a perfect choice. Red dwarf stars like TRAPPIST-1 are notorious for emitting flares and hard X-rays in their youth, but the system is just 40 light-years away and has seven Earth-sized worlds. Three of them are in the potentially habitable zone of the star. They are clustered closely enough to experience tidal forces and thus be geologically active. If intelligent life arises easily in the cosmos, then there’s a good chance it exists in the TRAPPIST-1 system.
Earth may have had a Saturn-like ring system long ago, created from the debris of a passing asteroid that our planet tore apart.
Astronomers have solid evidence for the existence of stellar-mass black holes and supermassive black holes. However, evidence for Intermediate Black Holes (IMBHs) is more elusive. Their existence remains hypothetical.

Scientists at NASA's Jet Propulsion Laboratory have recreated spider-like araneiform terrain, a geologic formation found on Mars, in a lab on Earth.
The most comprehensive map of clouds on Mars includes a variety of cloud patterns, including some that are unlike anything seen on Earth.
A pair of black hole jets powered by a supermassive black hole span far beyond their host galaxy — potentially affecting the cosmic web around it.
Astronomers have seen the largest jets ever found erupting from a black hole. The giant jet system Porphyrion is 23 million light-years long, equal to 140 side-by-side Milky Way galaxies.
Roberta Bondar knew that she would not be able to hear birds, let alone seen them from space, but when she really thought about it, their absence struck her deeply.
NASA's Curiosity rover has captured a spectacular sight from the surface of Mars: The first-ever photo of Earth alongside the Red Planet's moon Phobos.

From the arrival of the Earth obversation satellite Sentinel-2C in July 2024 and the first fit-check to launch from Europe’s Spaceport in French Guiana, this timelapse shows how the third Sentinel-2 satellite was prepared for launch. The last Vega rocket, flight VV24, lifted off on 5 September at 03:50 CEST (4 September 22:50 local time).
Located in the constellation Ursa Major, roughly 300 light-years from Earth, is the Sun-like star HD 118203 (Liesma). In 2006, astronomers detected an exoplanet (HD 118203 b) similar in size and twice as massive as Jupiter that orbits very closely to Liesma (7% of the distance between Earth and the Sun), making it a “Hot Jupiter.” In a recent study, an international team of astronomers announced the detection of a second exoplanet in this system: a Super Jupiter with a wide orbit around its star. In short, they discovered a “Cold Super-Jupiter” in the outskirts of this system.
In February 2016, scientists at the Laser Interferometer Gravitational-wave Observatory (LIGO) confirmed they made the first-ever detection of gravitational waves (GWs). These events occur when massive objects like neutron stars and black holes merge, sending ripples through spacetime that can be detected millions (and even billions) of light-years away. Since the first event, more than 100 GW events have been confirmed by LIGO, the Advanced VIRGO collaboration, and the Kamioka Gravitational Wave Detector (KAGRA).
A SpaceX Falcon 9 rocket is set to launch two European navigation satellites tonight (Sept. 17). It will be the 22nd flight for this particular booster.
Americans are famously fond of their guns. So it should come as no surprise that a team of NASA scientists has devised a way to “shoot” a modified type of sensor into the soil of an otherworldly body and determine what it is made out of. That is precisely what Sang Choi and Robert Moses from NASA’s Langley Research Center did, though their bullets are miniaturized spectrometers rather than hollow metal casings.
Is it time for space lasers yet? Almost.
