This illustration shows how black hole jets can be as large as the scale of the cosmic web itself, with Porphyrion, as illustrated here, setting a new cosmic record with its bipolar jets spanning 23–24 million light-years across. (Credit: Erik...
This illustration shows the Sun with a spacecraft, nominally the Parker Solar Probe, approaching it. In reality, the Parker Solar Probe, even at closest approach, is many solar diameters away from the Sun’s photosphere itself. No human-created spacecrafts has ever...
This composite image of NIRCam and MIRI data reveals the star-forming region known as Digel cloud 2s: a sub-complex of Digel cloud 2. Located 58,000 light-years away from the galactic center, it represents the highest-resolution image of stars forming in...
The Many Worlds Interpretation of quantum mechanics holds that there are an infinite number of parallel universes that exist, holding all possible outcomes of a quantum mechanical system, and that making an observation simply chooses one path. This interpretation is...
This graph shows the historical tropical cyclone frequency as a function of day of the year, with all tropical cyclones shown in red and hurricane-strength storms only shown in yellow. The background shows Hurricane Francie over the Gulf of Mexico...
The traditional model of an atom, now more than 100 years old, is of a positively charged nucleus orbited by negatively charged electrons. Although the outdated Bohr model is where this picture comes from, the size of the atom itself...
If you measure the expansion rate of the Universe using an early relic method, like the light from the CMB (top right), you get a value of around 67 km/s/Mpc. If you measure it by constructing a distance ladder (below...
This photometrically derived image of galaxy JADES-GS-z13-1-LA, as acquired with a variety of JWST NIRCam photometric filters, showcases a bright galaxy that has no signs of light at wavelengths below ~1.7 microns. The intergalactic medium is extraordinarily efficient at blocking...
This image shows galaxy NGC 3227, at left, with its neighbor NGC 3226, as viewed in optical light by the Hubble Space Telescope. Despite copious features common to spiral galaxies, including rich dust lanes, a bright central bulge, and new...
There are many sights in Earth’s night sky that have been witnessed by humans that don’t have a clear and compelling scientific explanation. But an “unidentified object” doesn’t necessarily mean aliens, and might be evidence of an entity, government/military-based or...
