NGC 2467, also known as the “Skull and Crossbones Nebula,” is a region where new stars are being born. Some people think it looks like a grinning skull, while others see the face of a colorful mandrill.

The Lobster Nebula

hgastroblog@gmail.com — Sat, 14 Dec 2024 00:00:00 +0000

I don’t think it will overly tax your imagination to see why NGC 6357 is nicknamed the Lobster Nebula. Or perhaps you think it resemblances a crab more?

The Butterfly Nebula

hgastroblog@gmail.com — Sun, 01 Dec 2024 00:00:00 +0000

Near the bright star Sadr (grossly over exposed in the image) at the center of the Northern Cross lies the Butterfly Nebula. Its nickname comes from its intricate shape that somewhat resembles a butterfly with its delicate wings outstretched.

The Cat's Paw Nebula

hgastroblog@gmail.com — Sun, 17 Nov 2024 00:00:00 +0000

The lesser-known Cat’s Paw Nebula (officially NGC 6334) is a region teeming with activity – another stellar nursery where stars are born from swirling contracting clouds of gas and dust.

The Dumbbell Nebula

hgastroblog@gmail.com — Fri, 01 Nov 2024 00:00:00 +0000

The Dumbbell Nebula, also known as M27, is a stunning cloud of gas and dust, located about 1,360 light-years away from Earth. One of the brightest and most beautiful nebulae in the night sky, it is especially known for its vibrant colors and distinctive shape, which resembles a dumbbell or an hourglass.

The Crab Nebula

hgastroblog@gmail.com — Wed, 17 Apr 2024 00:00:00 +0000

M1, the Crab Nebula, is the debris left by the death of a massive star when it exploded in a brilliant flash of light and energy nearly a thousand years ago. We can see many intricate details in the remains left by that supernova – wispy tendrils of gas and dust intertwine illuminated by the intense radiation emitted by the pulsar at its core.

The Jellyfish Nebula

hgastroblog@gmail.com — Fri, 01 Mar 2024 00:00:00 +0000

The Helix Nebula

hgastroblog@gmail.com — Mon, 01 Jan 2024 00:00:00 +0000

The Helix Nebula is a stunning example of a planetary nebula -— a glowing shell of ionized gas expelled by a dying star. The star expels its outer layers of gas, leaving only its small, hot core. Radiation from the core energizes that gas, causing it to glow in a rainbow of colors. About 650 light-years away, the Helix is one of the closest and brightest such nebulae.

The Heart and Soul of the Night Sky

hgastroblog@gmail.com — Fri, 08 Dec 2023 00:00:00 +0000

Is the heart and soul of our Galaxy located in the northern constellation Cassiopeia? Possibly not, but that is where two bright emission nebulas nicknamed Heart and Soul can be found – soulmates you could say. (Groan)

The Omega Nebula

hgastroblog@gmail.com — Fri, 17 Nov 2023 00:00:00 +0000

M17, another vast region of interstellar gas and dust, is most commonly known as the Omega Nebula or the Swan Nebula. The complex measures 15 light-years across and is about 5,000 light-years from Earth.

The Wizard Nebula

hgastroblog@gmail.com — Fri, 03 Nov 2023 00:00:00 +0000

The Wizard Nebula is a cosmic cloud surrounding open star cluster NGC 7380. Over the years it has earned its sorcerous nickname because of its similarity in appearance to a medieval magician in a pointed hat. (It does take a little imagination!)

The Tulip Nebula

hgastroblog@gmail.com — Sun, 15 Oct 2023 00:00:00 +0000

The Tulip Nebula is a glowing cloud of interstellar gas and dust and gets its name from the flower it appears to resemble in photographs. While a pretty sight itself, the Tulip has an interesting neighbor.

The Eagle Nebula M16, one of the brightest night sky nebulae, is an area where stars are actively forming. It is filled with dark regions and globules, including a peculiar dark column named the “Stellar Spire”. Of special note are the “Pillars of Creation” made famous by an early (1995) picture from the Hubble Space Telescope. The pillars and spire are collapsing clouds of dust and gas being sculpted by intense starlight from newly formed hot stars.

The Rosette Nebula

hgastroblog@gmail.com — Mon, 08 May 2023 00:00:00 +0000

The Rosette Nebula is one of the more spectacular nebulae in the night sky. It is a huge cloud of glowing gas heated and ionized by stars created only about five million years ago when a giant molecular cloud collapsed to form a new cluster of stars.

Thor's Helmet

hgastroblog@gmail.com — Sun, 22 Jan 2023 00:00:00 +0000

The Pelican Nebula

hgastroblog@gmail.com — Fri, 18 Nov 2022 00:00:00 +0000

The Pelican Nebula is an emission nebula whose outlines somewhat resemble the namesake bird. The nebula’s appearance is defined by dark dust clouds that outline the pelican’s long bill and eye, and by bright clouds of ionized gas that form the curved shape of the pelican’s head and neck. The pelican’s body and wing are formed by a complex mixture of bright nebulosity intermixed with dark dust clouds, as is the pouch hanging down from the bill.

The Elephant's Trunk Nebula

hgastroblog@gmail.com — Sat, 05 Nov 2022 00:00:00 +0000

The Elephant’s Trunk Nebula (IC 1396A) is a twisted sinuous structure of interstellar gas and dust that we see back-lit and ionized by intense radiation coming from a nearby massive star. Red light from ionized hydrogen makes it stand out amid the other streams and swirls of dark nebulae.

The Iris Nebula

hgastroblog@gmail.com — Sat, 15 Oct 2022 00:00:00 +0000

The Iris Nebula NGC 7023 looks like a celestial blossom. It is a bright reflection nebula whose trademark glowing blue color results from the scattered light of its central star.

The Cocoon Nebula

hgastroblog@gmail.com — Thu, 15 Sep 2022 00:00:00 +0000

The Cocoon Nebula, IC 5146, is a cluster of stars involved in a bright emission/reflection nebula riddled by filaments of dark nebula.
