What role will F-15 jets play in the future of supersonic flight?
In recent years, astrophysicists have discovered supermassive black holes (SMBH) in the early Universe that are much larger than they should be. Black hole growth is restrained by the Eddington Mass Limit, a cap on the growth rate of black holes. But objects can exceed this limit in certain circumstances, and that's called super-Eddington accretion. san Super-Eddington accretion explain these early SMBH?
The next Star Wars show from Lucasfilm Animation sees the fallen Sith lord build a criminal empire right under the Empire's nose.
The Lego Technic NASA Artemis has a few nifty tricks up its sleeve.
Unistellar co-founder tells Space.com about how citizen scientists are using smart telescopes to engage in planetary defense.
The moon will be closest to the Pleiades in the hours following sunset.
In our galaxy, a supernova explodes about once or twice each century. But historical astronomical records show that the last Milky Way core-collapse supernova seen by humans was about 1,000 years ago. That means we've missed a few.

Watch the keynote address by ESA Director General Josef Aschbacher at the 18th European Space Conference in Brussels.
A team of astronomers have used a new AI-assisted method to search for rare astronomical objects in the Hubble Legacy Archive. The team sifted through nearly 100 million image cutouts in just two and a half days, uncovering nearly 1400 anomalous objects, more than 800 of which had never been documented before.
The Artemis 2 moon mission's SLS rocket is on the pad at Kennedy Space Center for testing ahead of a possible Feb. 6 launch, and you can watch it 24/7 via this livestream.
The Carson RD 10x50 binoculars are a good all-rounder, but didn't shine when it came to stargazing.
Hunt for the names of mysterious dwarf planets, most of which orbit on the fringes of our solar system
The views of the setting sun are just as spectacular from space as they are on Earth.
Lately we’ve been reporting about a series of studies on the Habitable Worlds Observatory (HWO), NASA’s flagship telescope mission for the 2040s. These studies have looked at the type of data they need to collect, and what the types of worlds they would expect to find would look like. Another one has been released in pre-print form on arXiv from the newly formed HWO Technology Maturation Project Office, which details the technology maturation needed for this powerful observatory and the “trade space” it will need to explore to be able to complete its stated mission.
The European Space Agency discussed plans for its record budget as the 18th European Space Conference began in Brussels, Belgium on 27 January.
"It is exciting to think that Little Red Dots may represent the first direct observational evidence of the birth of the most massive black holes in the universe."
There’s a bright side to every situation. In 2032, the Moon itself might have a particularly bright side if it is blasted by a 60-meter-wide asteroid. The chances of such an event are still relatively small (only around 4%), but non-negligible. And scientists are starting to prepare both for the bad (massive risks to satellites and huge meteors raining down on a large portion of the planet) and the good (a once in a lifetime chance to study the geology, seismology, and chemical makeup of our nearest neighbor). A new paper from Yifan He of Tsinghua University and co-authors, released in pre-print form on arXiv, looks at the bright side of all of the potential interesting science we can do if a collision does, indeed, happen.
This coming July, Venus could plow through the dust generated by an asteroid breakup thousands of years ago, potentially sparking an impressive meteor shower.
The first images from the Meteosat Third Generation-Sounder satellite have been shared at the European Space Conference in Brussels, showing how the mission will provide data on temperature and humidity, for more accurate weather forecasting over Europe and northern Africa.
How long did it take to establish the water content within Jupiter’s Galilean moons, Io and Europa? This is what a recent study published in The Astrophysical Journal hopes to address as a team of scientists from the United States and France investigated the intricate processes responsible for the formation and evolution of Io and Europa. This study has the potential to help scientists better understand the formation and evolution of two of the most unique moons in the solar system, as Io and Europa are known as the most volcanically active body in the solar system and an ocean world estimated to contain twice the volume of Earth’s oceans, respectively.
"This is one of the most exciting results from Solar Orbiter so far."
