M76 (ou NGC 650) est une nébuleuse planétaire située dans la constellation de Persée. Elle est également connue sous le nom du Petit Haltère (ou Little Dumbbell), sa forme rappelant celle de la nébuleuse de l'Haltère (M27, aussi connue sous le nom de Dumbbell). M76 est l'un des objets les moins lumineux du catalogue de Messier.

The Little Dumbbell Nebula, also known as Messier 76, NGC 650/651, the Barbell Nebula, or the Cork Nebula, is a planetary nebula in the northern constellation of Perseus. It was discovered by Pierre Méchain in 1780 and included in Charles Messier's catalog of comet-like objects as number 76.

The Little Dumbbell Nebula, also known as Messier 76 (M76), NGC 650/651, is a planetary nebula in northern constellation Perseus. Distance to M76 is currently estimated as 780 parsecs or 2,500 light years. The total nebula shines at the apparent magnitude of +10.1. The Little Dumbbell Nebula derives its common name from its resemblance to the Dumbbell Nebula (M27) in Vulpecula. It was originally thought to consist of two separate emission nebulae so bears New General Catalog numbers NGC 650 and 651.

天皇両陛下は、本当に心から心配されて、ご高齢、多忙、かつ遠方なのに、実際に行く。人間である被災者たちの"心の拠り所"になる。

"寄り添う","支え合う" 人間とはこういうものだ。

どうしてだろう。人間としてこの様に、当然である"支え合い"ができない世界に陥ってしまっている。肉親、友人でさえ。わたしはキミの笑顔が見たい。

Their Majesties the #Emperor and #Empress are truly concerned and have gone to the disaster sites, despite their advanced age, busy schedules, and distance. They are a source of #emotional support for the victims, who are also #humanbeings .

To be " #close " and " #support #eachother " is what it means to be human.

Why has it come to this? We have fallen into a world where we are unable to " #support each other," something that should be #natural for #human beings. Even among family and friends. I want to see your smile.

In celebration of the 34th anniversary of the launch of NASA's legendary Hubble Space Telescope on April 24, astronomers took a snapshot of the Little Dumbbell Nebula (also known as Messier 76, M76, or NGC 650/651) located 3,400 light-years away in the northern circumpolar constellation Perseus. The photogenic nebula is a favorite target of amateur astronomers.

M76 is classified as a planetary nebula, an expanding shell of glowing gases that were ejected from a dying red giant star. The star eventually collapses to an ultra-dense and hot white dwarf. A planetary nebula is unrelated to planets, but have that name because astronomers in the 1700s using low-power telescopes thought this type of object resembled a planet.

M76 is composed of a ring, seen edge-on as the central bar structure, and two lobes on either opening of the ring. Before the star burned out, it ejected the ring of gas and dust. The ring was probably sculpted by the effects of the star that once had a binary companion star. This sloughed off material created a thick disk of dust and gas along the plane of the companion's orbit. The hypothetical companion star isn't seen in the Hubble image, and so it could have been later swallowed by the central star. The disk would be forensic evidence for that stellar cannibalism.

The primary star is collapsing to form a white dwarf. It is one of the hottest stellar remnants known at a scorching 250,000 degrees Fahrenheit, 24 times our Sun's surface temperature.
The sizzling white dwarf can be seen as a pinpoint in the center of the nebula. A star visible in projection beneath it is not part of the nebula.


Pinched off by the disk, two lobes of hot gas are escaping from the top and bottom of the "belt," along the star's rotation axis that is perpendicular to the disk. They are being propelled by the hurricane-like outflow of material from the dying star, tearing across space at two million miles per hour. That's fast enough to travel from Earth to the Moon in a little over seven minutes! This torrential "stellar wind" is plowing into cooler, slower-moving gas that was ejected at an earlier stage in the star's life, when it was a red giant. Ferocious ultraviolet radiation from the super-hot star is causing the gases to glow. The red color is from nitrogen, and blue is from oxygen.


Given our solar system is 4.6 billion years old, the entire nebula is a flash in the pan by cosmological timekeeping. It will vanish in about 15,000 years.

Hubble's Star Trekking

Since its launch in 1990 Hubble has made 1.6 million observations of over 53,000 astronomical objects. To date, the Mikulski Archive for Space Telescopes at the Space Telescope Science Institute in Baltimore, Maryland holds 184 terabytes of processed data that is science-ready for astronomers around the world to use for research and analysis. Since 1990, 44,000 science papers have been published from Hubble observations. The space telescope is the most scientifically productive space astrophysics mission in NASA history. The demand for using Hubble is so high it is currently oversubscribed by a factor of six-to-one.

Most of Hubble's discoveries were not anticipated before launch, such as supermassive black holes, the atmospheres of exoplanets, gravitational lensing by dark matter, the presence of dark energy, and the abundance of planet formation among stars.

Hubble will continue research in those domains and capitalize on its unique ultraviolet-light capability on such topics as solar system phenomena, supernovae outbursts, composition of exoplanet atmospheres, and dynamic emission from galaxies. And Hubble investigations continue to benefit from its long baseline of observations of solar system objects, stellar variable phenomena and other exotic astrophysics of the cosmos.

NASA's James Webb Space Telescope was designed to be meant to be complementary to Hubble, and not a substitute. Future Hubble research also will take advantage of the opportunity for synergies with Webb, which observes the universe in infrared light. The combined wavelength coverage of the two space telescopes expands on groundbreaking research in such areas as protostellar disks, exoplanet composition, unusual supernovae, cores of galaxies and chemistry of the distant universe.

The Hubble Space Telescope has been operating for over three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA's Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope and mission operations. Lockheed Martin Space, based in Denver, Colorado, also supports mission operations at Goddard. The Space Telescope Science Institute in Baltimore, Maryland, which is operated by the Association of Universities for Research in Astronomy, conducts Hubble science operations for NASA.

In celebration of the 34th anniversary of the launch of NASA’s legendary Hubble Space Telescope, astronomers took a snapshot of the Little Dumbbell Nebula, also known as Messier 76, or M76, located 3,400 light-years away in the northern circumpolar constellation Perseus. The name 'Little Dumbbell' comes from its shape that is a two-lobed structure of colorful, mottled, glowing gases resembling a balloon that’s been pinched around a middle waist. Like an inflating balloon, the lobes are expanding into space from a dying star seen as a white dot in the center. Blistering ultraviolet radiation from the super-hot star is causing the gases to glow. The red color is from nitrogen, and blue is from oxygen.

La nébuleuse planétaire de la Petite Haltère M 76 (NGC 650) est située à 3 400 années-lumière de la Terre dans la constellation circumpolaire nord de Persée (Perseus). Composée d'un anneau vu par la tranche, sa structure comprend une barre centrale deux lobes sur chaque ouverture de l'anneau. Avant que l’étoile ne s’éteigne, celle-ci a éjecté l’anneau de gaz et de poussière, probablement sculpté par les effets de l’étoile ayant eu autrefois une étoile compagne binaire. Ce matériau éliminé a créé un épais disque de poussière et de gaz le long du plan de l’orbite du compagnon. Si cette hypothétique étoile compagnon n’est pas visible ici, elle aurait donc pu être avalée plus tard par l’étoile centrale.

L'étoile primaire s'effondre pour former une naine blanche, l’un des restes stellaires les plus chauds connus, avec une température torride de 120 000 degrés Celsius, soit 24 fois la température de la surface de notre Soleil. La naine blanche grésillante peut être vue comme un point précis au centre de la nébuleuse (l'étoile visible en dessous ne faisant pas partie de la nébuleuse.

Pincés par le disque, deux lobes de gaz chaud s’échappent du haut et du bas de la ceinture, le long de l’axe de rotation de l’étoile qui est perpendiculaire au disque, propulsés par l’écoulement de matière semblable à un ouragan provenant de l’étoile mourante, traversant l’espace à 3 millions de k/h. Ce vent stellaire torrentiel s’abat sur un gaz plus froid et plus lent, éjecté à un stade antérieur de la vie de l’étoile, lorsqu’elle était une géante rouge. La nébuleuse entière est comme un "feu de paille" cosmologique, puisqu'elle disparaîtra dans environ 15 000 ans.

Description de l'image
Le nom de la nébuleuse du Petit Haltère vient de sa forme, qui est une structure à deux lobes de gaz incandescents colorés et marbrés ressemblant à un ballon pincé autour d'une taille moyenne. Comme un ballon qui se gonfle, les lobes s'étendant dans l'espace à partir d'une étoile mourante (une naine), vue comme un point blanc au centre. Le rayonnement ultraviolet fulgurant de l’étoile super chaude fait briller les gaz, la couleur rouge venant de l’azote et la couleur bleue de l’oxygène (cf. NASA, ESA, STScI, A. Pagan STScI).

Ne pas confondre cette nébuleuse planétaire avec elle de l'Haltère M 27 (NGC 6853), située à 1 250 années-lumière de la Terre dans la constellation du Petit Renard (Vulpecula).
