Euclid shows us a spectacularly panoramic and detailed view of the Horsehead Nebula, also known as Barnard 33 and part of the constellation Orion. In Euclid’s new observation of this stellar nursery, scientists hope to find many dim and previously unseen Jupiter-mass planets in their celestial infancy, as well as young brown dwarfs and baby stars.
Nearly a year ago, NASA successfully smashed an asteroid for the first time, in a landmark test to see whether we could divert a killer space rock before disaster — but now, the asteroid in question is behaving strangely. As New Scientist reports, a schoolteacher and his pupils seem to have discovered that the orbit of Dimorphos, the space rock socked by the Double Asteroid Redirection Test (DART) last September, has apparently continued slowing down, unexpectedly, in the year since the refrigerator-sized craft smashed into it.
Researchers from Japan predict, based on computer simulations, the likely existence of an Earth-like planet in the distant Kuiper Belt. There are many unexplained anomalies in the orbits and distribution of trans-Neptunian objects, small celestial bodies located at the outer reaches of the solar system. Now, based on detailed computer simulations of the early outer solar system, researchers from Japan predict the possibility of an undiscovered Earth-like planet beyond Neptune orbiting the Sun. Should this prediction come true, it could revolutionize our understanding of the history of the solar system.
The Japan Aerospace Exploration Agency’s (JAXA) X-Ray Imaging and Spectroscopy Mission (XRISM) lifted off on a H-IIA rocket from the Tanegashima Space Center in Japan at 08:42 JST / 00:42 BST / 01:42 CEST on 7 September 2023. The successful launch marks the beginning of an ambitious mission to explore the growth of galaxy clusters, the chemical make-up of the Universe, and the extremes of spacetime. XRISM is a collaboration between JAXA and NASA, with significant participation from ESA.

This week’s image is from the Hubble Space Telescope. It shows a fantastic array of colors from a portion of NGC 6530, which is about 4,350 light-years from Earth.
A portion of the open cluster NGC 6530 appears as a roiling wall of smoke studded with stars in this image from the NASA/ESA Hubble Space Telescope…The cluster is set within the larger Lagoon Nebula, a gigantic interstellar cloud of gas and dust. It is the nebula that gives this image its distinctly smokey appearance; clouds of interstellar gas and dust stretch from one side of this image to the other.
You can also watch this short video that pans over the cluster.

A new crew departed Earth for the International Space Station (ISS) at 3:27am ET today from NASA’s Kennedy Space Center in Florida via a SpaceX Falcon 9 rocket. The crew includes:
NASA astronaut Jasmin Moghbeli,
ESA (European Space Agency) astronaut Andreas Mogensen,
JAXA (Japan Aerospace Exploration Agency) astronaut Satoshi Furukawa, and
Roscosmos cosmonaut Konstantin Borisov.
The new crew should be onboard the ISS tomorrow morning, bringing the number of occupants at the station to 11 until 4 crew members return to Earth in a few days.
Russia is probably happy to have attention back on the ISS rather than the Moon for the moment. It has not been a good week for the Russian space program.

This week’s image is from NASA/European Space Agency’s (ESA) Hubble Space Telescope. It shows the glowing galaxy NGC 6684, which is around 44 million light-years from Earth.
This oddly shaped galaxy is explained on the ESA’s website:
Lenticular galaxies like NGC 6684 (lenticular means lens-shaped) possess a large disc but lack the prominent spiral arms of galaxies like the Andromeda Galaxy. This leaves them somewhere between elliptical galaxies and spiral galaxies, and lends these galaxies a diffuse, ghostly experience. NGC 6684 also lacks the dark dust lanes that thread through other galaxies, adding to its spectral, insubstantial appearance.
