Wide-field View of The Serpent's Nebula | European Southern Observatory
This image from the Digitized Sky Survey (DSS) shows the area around the Serpens Nebula. The Serpens star-forming region is a compact region of star formation. At a distance of about 1,300 light-years, it is close enough for detailed, spatially-resolved studies of its individual young stellar objects.
The emission nebula Sh2-54 glows brightly in this image from the SMARTS 0.9-meter Telescope at Cerro Tololo Inter-American Observatory (CTIO), a Program of the National Science Foundation’s NOIRLab. Gathering the fine details of this particular image required almost twenty minutes of observations and three different wavelength filters. Situated within the constellation of Serpens (The Serpent), Sh2-54 forms part of a much wider nebulosity which includes the famous Eagle Nebula. Serpens is a unique constellation, the only one of the official 88 used today that is split into two unconnected parts: Serpens Caput—the Serpent’s Head—and Serpens Cauda—The Serpent’s Tail.

Newly Detected Comet C/2023 P1 (Nishimura): Tails Growing Near Sun
Comet Nishimura is expanding. More precisely, the tails of comet C/2023 P1 (Nishimura) are growing as it nears the Sun. Discovered in August 2023, the comet is already near naked eye brightness as it now moves inside the Earth's orbit. The comet will be nearest the Earth next week, but nearest the Sun the week after—on September 17, 2023. Speculation holds that expelled ice and dust from Comet Nishimura's last visit to the inner Solar System may have created the Sigma Hydrids meteor shower which peaks yearly in December. If so, then this meteor shower may become more active, refreshed with new comet debris.
This image of Comet Nishimura was captured from Edgewood, New Mexico, USA four nights ago, showing a long ion tail structured by interactions with the solar wind. The solar wind is a stream of charged particles released from the upper atmosphere of the Sun, called the corona.
Look for this comet near your eastern horizon just before sunrise for the next few mornings, but very near your western horizon just after sunset next week—as its coma continues to brighten and its tails continue to grow.
C/2023 P1 (Nishimura) is a long-period comet discovered by Hideo Nishimura on Aug. 12, 2023. With an observation arc of seven months, the orbital period of the comet is estimated to be 434 years. An eccentricity of 0.996 gives the comet a semi-major axis (average distance from the Sun) of about 57 astronomical units (AU), which is comparable to the average distance of Eris at 68 AU. The comet will not leave the Solar System and will come to aphelion (farthest distance from the Sun) in the year 2227.
1 astronomical unit (AU) = equal to 150 million kilometers (93 million miles) or 8.3 light-minutes
An astronomical unit is a unit of length, roughly the distance from Earth to the Sun.
Japanese amateur astronomer Hideo Nishimura discovered the comet in images he obtained using a 200-mm f/3 telephoto lens mounted on a Canon EOS 6D on Aug. 12, 2023, when the comet was 1 AU from the Sun.

NASA's Michoud Assembly Facility in Louisiana: Supporting Human Spaceflight
On September 7, 1961, NASA named the Michoud Assembly Facility (MAF) to be the sole manufacturing plant for building human space flight vehicles. This year MAF is responsible for producing space flight hardware for Apollo, Shuttle, and now Artemis. Throughout the years, MAF has endured several natural disasters which tested their resiliency—a test they continue to pass time and time again.

Astronauts Moghbeli & Rubio Talk to Georgia Students | International Space Station
Aboard the International Space Station, Expedition 69 Flight Engineers Frank Rubio and Jasmin Moghbeli of NASA answered pre-recorded questions about life and work on the orbiting laboratory during an in-flight event Sept. 7, 2023, with students at Dames Ferry Elementary School in Gray, Georgia. Rubio and Moghbeli are in the midst of science missions living and working aboard the microgravity laboratory to advance scientific knowledge and demonstrate new technologies. Such research benefits people on Earth and lays the groundwork for future human exploration through the agency’s Artemis missions, which will send astronauts to the Moon to prepare for future expeditions to Mars.

Using NASA’s Neil Gehrels Swift Observatory, which launched in 2004, scientists have discovered a black hole in a distant galaxy repeatedly nibbling on a Sun-like star. The object heralds a new era of Swift science made possible by a novel method for analyzing data from the satellite’s X-ray Telescope (XRT).
When a star strays too close to a monster black hole, gravitational forces create intense tides that break the star apart into a stream of gas. The leading edge swings around the black hole, and the trailing edge escapes the system. These destructive episodes are called tidal disruption events. Astronomers see them as flares of multiwavelength light created when the debris collides with a disk of material already orbiting the black hole.
Recently, astronomers have been investigating variations on this phenomena, which they call partial or repeating tidal disruptions.
During these events, every time an orbiting star passes close to a black hole, the star bulges outward and sheds material, but survives. The process repeats until the star looses too much gas and finally breaks apart. The characteristics of the individual star and black hole system determine what kind of emission scientists observe, creating a wide array of behaviors to categorize.
On June 22, 2022, XRT captured Swift J0230 for the first time. It lit up in a galaxy around 500 million light-years away in the northern constellation Triangulum. Swift’s XRT has observed nine additional outbursts from the same location roughly every few weeks.
Scientists propose that Swift J0230 is a repeating tidal disruption of a Sun-like star orbiting a black hole with over 200,000 times the Sun’s mass. They estimate the star loses around three Earth masses of material on each pass. This system provides a bridge between other types of suspected repeating disruptions and allowed scientists to model how interactions between different star types and black hole sizes affect what we observe.
Swift J0230’s discovery was possible thanks to a new, automated search of XRT observations called the Swift X-ray Transient Detector.
After the instrument observes a portion of the sky, the data is transmitted to the ground, and the program compares it to previous XRT snapshots of the same spot. If that portion of the X-ray sky has changed, scientists get an alert. In the case of Swift J0230, astronomers were able to rapidly coordinate additional observations of the region.
