SN 2026dix is a supernova discovered on February 16, 2026 by the MASTER robotic telescope network, appearing within the spiral arms of the galaxy NGC 3913 in Ursa Major. NGC 3913 is a faint, face-on spiral galaxy located about 54 million light-years away. Some early reports and spectroscopic follow-up have classified SN 2026dix as a Type IIb “stripped-envelope” core-collapse supernova, a category in which the exploding star had lost most, but not all, of its outer hydrogen envelope before detonating. Because this event occurred very recently, this description relies on preliminary discovery and follow-up reports rather than a fully settled literature; readers should treat specific figures (brightness, exact distance, and classification) as subject to revision as further observations and analysis are published.

Messier 101, the Pinwheel Galaxy, is a large, face-on “grand design” spiral galaxy in Ursa Major, cataloged as NGC 5457. Distance estimates generally cluster around 21-25 million light-years, and at that distance its roughly 170,000-light-year diameter makes it noticeably larger than the Milky Way. Gravitational interactions with several smaller companion galaxies have given its spiral arms an asymmetric, slightly lopsided structure, and its arms are richly dotted with star-forming HII regions. M101 has hosted several observed supernovae, including the well-studied SN 2011fe. For astrophotographers it is a favorite luminance/RGB target, rewarding long integration time to...

For astrophotographers it is a favorite luminance/RGB target, rewarding long integration time to resolve the delicate spiral structure and pink-tinged star-forming knots strung along its arms against a relatively faint overall surface brightness.

IC 443, nicknamed the Jellyfish Nebula, is a supernova remnant in the constellation Gemini, located near the star Eta Geminorum at the foot of the Twins. Estimates place it roughly 5,000 light-years away (with some studies suggesting closer to 6,000), giving it a true diameter on the order of 70 light-years; the explosion that created it likely occurred tens of thousands of years ago, though age estimates vary widely. The remnant is associated with a neutron star, and its shock front is seen colliding with adjacent molecular clouds, producing the tangled, tentacle-like filaments that give the nebula its name. Both Hα and O III narrowband filters are effective here, revealing the delicate shock-excited filaments against the surrounding star field, with the brighter western arc offering the most photogenic detail for amateur imagers.
