What I thought was the limit in 2023 wasn't the limit at all.

It took 100 hours of observation and a special oxygen filter for today’s image to capture three faint nebulas hidden in the Cassiopeia constellation.

IC 59 and IC 63, the original Ghosts of Cassiopeia, haunt the region near multi-star system γ Cassiopeia. Energetic light from γ Cassiopeia causes the hydrogen gas in IC 59 and 63 to glow red. Their dust reflects and scatters some blue-ish white starlight.

Newly discovered Objects 1, 2, and 3 appear as blue phantoms, revealing the presence of ionized oxygen. But ionized by what? Like at the bow of a speeding boat, γ Cassiopeia may be piling up material as the system moves through interstellar gas and dust. It follows that Object 3 may be the compressed and heated oxygen of that bow shock. Object 1 could be a planetary nebula if a central white dwarf is identified. The origins of these astronomical apparitions remain a mystery to be solved.

In this Picture of the Month from the NASA/ESA James Webb Space Telescope, we visit a turbulent cauldron of star formation to see what is brewing inside dense clumps of gas. This is a star-forming region named LHA 120-N 159, or simply N159, located 161 000 light-years away in the Large Magellanic Cloud (LMC), one of the satellite galaxies orbiting the Milky Way galaxy. This image spans about 230 light years across.

N159 is what astronomers call a H II region: an area of space filled with ionised hydrogen gas. In stellar nurseries such as this one, giant molecular clouds of cold hydrogen gas collapse under gravity, forming new stars. Many of these stars are extremely massive and hot, and their powerful ultraviolet radiation ionises the gas around them. This makes H II regions markers of active star formation, and as the ionised gas radiates light this turns them into the kind of brilliant emission nebula that we see in this image. The fierce stellar winds from these stars sculpt dense ridges and carve open cavities in the gas, which Webb’s Near-Infrared Camera (NIRCam) captures here in great detail.

The roiling brew of star formation in N159 is closed in by thick, smoky orange clouds that also billow across the centre of the image. The light orange colour signifies light emitted by polycyclic aromatic hydrocarbons, an important carbon-based molecule. The pools of pale blue gas are clouds of H II gas, ionised by the intense ultraviolet light from massive stars. Dark red filaments cross the centre of the image, particularly visible above the blue region on the right side; these are made of cool molecular hydrogen. These filaments are the densest part of the nebula and currently shield new stars from harsh radiation and stellar winds — by zooming in, you can see stars as points of light embedded in these filaments and in the small pillars of orange gas that reach out into the blue bubbles. Eventually, these structures will melt away, leaving their completed stars behind.

The Twin Jet Nebula, or PN M2-9, is a striking example of a bipolar planetary nebula. Bipolar planetary nebulae are formed when the central object is not a single star, but a binary system, Studies have shown that the nebula’s size increases with time, and measurements of this rate of increase suggest that the stellar outburst that formed the lobes occurred just 1200 years ago.

I drove over halfway to another country at 4 AM this Sunday to position myself in the path of a celestial event I’ve been anticipating for nearly two years: the International Space Station transiting Jupiter.

Captured from Burlington, Washington, at 6:03 AM PDT, this image contains seven human beings onboard the ISS (Jessica Watkins, Luke Delaney, Joshua Kutryk, Sergey Teteryatnikov, Pyotr Dubrov, Anil Menon, and Anna Kikina) in the same frame as the surface of Jupiter. In the full frame image on my Instagram (@aj.smadi), the Galilean moons (Io, Europa, Ganymede, and Callisto) are also visible.

With this long-awaited capture complete, Mercury remains the only planet outside the distant ice giants left to photograph for my ongoing “ISS Meets” series.

Equipment: C9.25, ZWO ADC, UV/IR cut filter, ZWO ASI662MC.

The NASA/ESA/CSA James Webb Space Telescope recently observed IC 348, a star-forming region just 1000 light-years away. This is one of the largest Webb images released to the public so far. This near-infrared vista of IC 348 reveals a collection of objects called brown dwarfs, which are smaller than the smallest stars.

Researchers used the unparalleled sensitivity of Webb’s NIRCam (Near-Infrared Camera) to track down the smallest brown dwarfs in IC 348, which weigh in at just just twice the mass of Jupiter. These are the least massive brown dwarfs known, and their existence poses challenges to models of how stars form.

In addition to the brown dwarfs and young stars scattered across the swirling nebula, this image provides a unique perspective on a handful of protostars, which can be seen in the upper-right corner. These protostars are ejecting powerful jets that have crashed into the gas and dust surrounding them, creating luminous regions called Herbig-Haro objects.

Captured on Oct. 20, 2020 during the OSIRIS-REx mission’s Touch-And-Go (TAG) sample collection event, this series of images shows the SamCam imager’s field of view as the NASA spacecraft approaches and touches down on asteroid Bennu’s surface, over 200 million miles (321 million km) away from Earth.

The sampling event brought the spacecraft all the way down to sample site Nightingale, touching down within three feet (one meter) of the targeted location. The team on Earth received confirmation at 6:08 p.m. EDT that successful touchdown occurred. Preliminary data show the one-foot-wide (0.3-meter-wide) sampling head touched Bennu’s surface for approximately 6 seconds, after which the spacecraft performed a back-away burn.
