I added buttons to my news page to allow going back a week, or search for older data. This cannot replace MAST, here for example search for "quintet" missed images labelled as NGC*. But it is quick.

Screenshot from the frontpage of the Open Journal of Astrophysics, featuring the following article informations. Title reads "Revisiting the Great Attractor: The Local Group's streamline trajectory, cosmic velocity and dynamical fate". Authors list: Richard Stiskalek, Harry Desmond, Stuart McAlpine, Guilhem Lavaux, Jens Jasche, Michael J. Hudson. Summary reads "The study revisits the Great Attractor concept, finding that it doesn't dominate the Local Group's cosmic velocity; multiple structures contribute to the motion, with no single attractor accounting for it". Dated February 17, 2026. Background image featuring an allsky map of the depth of the inferred Classical Great Attractor basin as a function of sky position in Galactic coordinates.

Great paper on the Great Attractor, just published by The Open Journal of Astrophysics

This image shows the Cocoon Nebula (IC 5146) as a glowing, heart-shaped cloud set against a dense backdrop of countless stars scattered across the Milky Way. The nebula's center is filled with warm reds, oranges, and golds, forming a luminous cocoon of gas and dust with soft, uneven edges that fade into the surrounding darkness. Embedded within this glowing cloud are many young stars, some appearing as bright white or bluish points, while others are hidden and revealed only through X-ray light detected by NASA's Chandra X-ray Observatory. These X-rays trace a cluster of newly formed, highly active stars concentrated near the nebula's core. The heart-shaped nebula itself shines through a mix of light emitted by these young stars and starlight reflected off surrounding dust. Optical data from two astrophotographers and infrared observations from NASA's Wide-field Infrared Survey Explorer provide depth and texture, revealing a sparkling star field and the thick, dusty structures where new stars continue to form.

Green outflows in front of bright blue to violet clouds, some dark clouds are also seen. One massive outflow lies horizontally coming out of a bright star. A smaller outflow is also horizontally to the lower left.

New frame of the Orion Molecular Cloud (OMC) from program 5804. The bright star at the top-middle part is the young stellar object HOPS 92. It is launching a massive outflow.
