Composite image of Messier 1 (Crab Nebula) by NASA's Spitzer and Hubble Space Telescopes, and NASA's Chandra X-ray Observatory
This photo shows a three colour composite of the well-known Crab Nebula (also known as Messier 1), as observed with the FORS2 instrument in imaging mode in the morning of November 10, 1999. It is the remnant of a supernova explosion at a distance of about 6,000 light-years, observed almost 1,000 years ago, in the year 1054. It contains a neutron star near its center that spins 30 times per second around its axis (see below). In this picture, the green light is predominantly produced by hydrogen emission from material ejected by the star that exploded. The blue light is predominantly emitted by very high-energy ("relativistic") electrons that spiral in a large-scale magnetic field (so-called synchrotron emission). It is believed that these electrons are continuously accelerated and ejected by the rapidly spinning neutron star at the centre of the nebula and which is the remnant core of the exploded star. This pulsar has been identified with the lower/right of the two close stars near the geometric center of the nebula, immediately left of the small arc-like feature, best seen in ESO Press Photo eso9948. Technical information: ESO Press Photo eso9948 is based on a composite of three images taken through three different optical filters: B (429 nm; FWHM 88 nm; 5 min; here rendered as blue), R (657 nm; FWHM 150 nm; 1 min; green) and S II (673 nm; FWHM 6 nm; 5 min; red) during periods of 0.65 arcsec (R, S II) and 0.80 (B) seeing, respectively. The field shown measures 6.8 x 6.8 arcminutes and the images were recorded in frames of 2048 x 2048 pixels, each measuring 0.2 arcseconds. North is up; East is left. #L
In commemoration of the 15th anniversary of NASA's Chandra X-ray Observatory, four newly processed images of supernova remnants dramatically illustrate Chandra's unique ability to explore high-energy processes in the cosmos. The images of the Tycho and G292.0+1.8 supernova remnants show how Chandra can trace the expanding debris of an exploded star and the associated shock waves that rumble through interstellar space at speeds of millions of miles per hour. The images of the Crab Nebula and 3C58 show how extremely dense, rapidly rotating neutron stars produced when a massive star explodes can create clouds of high-energy particles light years across that glow brightly in X-rays.
Heavily processed Hubble Space Telescope image of the interior of the Crab Nebula and its neutron star.
This new Hubble image - among the largest ever produced with the Earth-orbiting observatory - gives the most detailed view of the entire Crab Nebula ever. The Crab is among the most interesting and well studied objects in astronomy. This image is the largest image ever taken with Hubble's WFPC2 camera. It was assembled from 24 individual exposures taken with the NASA/ESA Hubble Space Telescope and is the highest resolution image of the entire Crab Nebula ever made.

. Spectral energy distribution of the Crab Nebula from soft to very high energy γ-rays. The Whipple spectrum above 500 GeV (Hillas et al. 1998) is also consistent with these measurements. The fit of the synchrotron component, using COMPTEL and LAT data (blue dashed line), is overlaid. The predicted IC spectra from Atoyan & Aharonian (1996) are overlaid for three different values of the mean magnetic field: 100 μG (solid red line), 200 μG (dashed green line), and the canonical equipartition field of the Crab Nebula 300 μG (dotted blue line).

Heavily processed Hubble Space Telescope image of the interior of the Crab Nebula and its neutron star.
This new Hubble image - One among the largest ever produced with the Earth-orbiting observatory - shows gives the most detailed view so far of the entire Crab Nebula ever made. The Crab is arguably the single most interesting object, as well as one of the most studied, in all of astronomy. The image is the largest image ever taken with Hubble's WFPC2 workhorse camera. The Crab Nebula is one of the most intricately structured and highly dynamical objects ever observed. The new Hubble image of the Crab was assembled from 24 individual exposures taken with the NASA/ESA Hubble Space Telescope and is the highest resolution image of the entire Crab Nebula ever made.
Messier 1 – the Crab Nebula
~6500 Lightyears away in Taurus. It is the remnant of a supernova that was observed as a Guest Star on 4 July 1054 by Chinese astronomers.
The mystery of why a star clearly visible in broad daylight was not recorded in Europe was something I looked into for my final year project. I found no answer!

Messier object No1 - The Crab Nebula. This is a remnant of a supernova which exploded in 1054 (Chinese and Arab astronomers witnessed the supernova). The Crab Nebula is in the constellation of Taurus (The Bull) and is around 6500 Light years from Earth.
RA: 05h 34m 31.94s, Dec: +22° 00′ 52.2″
The Crab Nebula (Messier 1, NGC 1952, Taurus A) is a supernova remnant and pulsar wind nebula in the constellation of Taurus. Discovered by English astronomer John Bevis in 1731, it corresponds with a bright supernova recorded by Chinese astronomers in 1054 AD as a guest star.
The central star in the nebula, the Crab Pulsar, is an optical pulsar (a type of neutron star) approximately 20 km in diameter, which formed from the collapse of its progenitor star during the supernova.

Edited Webb Space Telescope image of the Crab nebula.
Original caption: The NASA/ESA/CSA James Webb Space Telescope dissected the Crab Nebula’s structure, aiding astronomers as they continue to evaluate leading theories about the supernova remnant’s origins. With the data collected by Webb’s NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument), a team of scientists were able to closely inspect some of the Crab Nebula’s major components. For the first time ever, astronomers mapped the warm dust emission throughout this supernova remnant. Represented here as fluffy magenta material, the dust grains form a cage-like structure that is most apparent toward the lower left and upper right portions of the remnant. Filaments of dust are also threaded throughout the Crab’s interior and sometimes coincide with regions of doubly ionised sulphur (sulphur III), coloured in green. Yellow-white mottled filaments, which form large loop-like structures around the supernova remnant’s centre, represent areas where dust and doubly ionised sulphur overlap. The dust’s cage-like structure helps constrain some, but not all of the ghostly synchrotron emission represented in blue. The emission resembles wisps of smoke, most notable toward the Crab’s centre. The thin blue ribbons follow the magnetic field lines created by the Crab’s pulsar heart — a rapidly rotating neutron star.

A composite image of the Crab Nebula features X-rays from Chandra (blue and white), optical data from Hubble (purple), and infrared data from Spitzer (pink). The Crab Nebula is powered by a quickly spinning, highly magnetized neutron star called a pulsar, which was formed when a massive star ran out of its nuclear fuel and collapsed. The combination of rapid rotation and a strong magnetic field in the Crab generates an intense electromagnetic field that creates jets of matter and anti-matter moving away from both the north and south poles of the pulsar, and an intense wind flowing out in the equatorial direction.

M1, the Crab Nebula taken at F/10 for 30 minutes. Had some tracking issues so the stars are not quite round. Ideally this is probably an object that would benefit for 60 minutes or longer exposure time.
