Man sees what he wants to see, and so it is with the Dark Nebula LDN 1235. This collection of dust in the constellation Cepheus is very reminiscent of a shark. At just 650 light years away, it is just around the corner.

Happy Wednesday! It's time for an astronomy word of the day!

Asterism - an asterism is any prominent star pattern that isn’t a whole constellation, such as the Northern Cross or the Big Dipper (pictured below)

The Cone Nebula from Hubble Image Credit: Hubble Legacy Archive, NASA, ESA - Processing & Licence: Judy Schmidt

Explanation: Stars are forming in the gigantic dust pillar called the Cone Nebula. Cones, pillars, and majestic flowing shapes abound in stellar nurseries where natal clouds of gas and dust are buffeted by energetic winds from newborn stars. The Cone Nebula, a well-known example, lies within the bright galactic star-forming region NGC 2264. The Cone was captured in unprecedented detail in this close-up composite of several observations from the Earth-orbiting Hubble Space Telescope. While the Cone Nebula, about 2,500 light-years away in Monoceros, is around 7 light-years long, the region pictured here surrounding the cone’s blunted head is a mere 2.5 light-years across. In our neck of the galaxy that distance is just over half way from our Sun to its nearest stellar neighbors in the Alpha Centauri star system. The massive star NGC 2264 IRS, seen by Hubble’s infrared camera in 1997, is the likely source of the wind sculpting the Cone Nebula and lies off the top of the image. The Cone Nebula’s reddish veil is produced by dust and glowing hydrogen gas.

Please, forecast, be right about tomorrow night.

(For where we live, that's clear).

The Orion You Can Almost See Image Credit & Copyright: Michele Guzzini

Explanation: Do you recognize this constellation? Although it is one of the most recognizable star groupings on the sky, this is a more full Orion than you can see – an Orion only revealed with long exposure digital camera imaging and post- processing. Here the cool red giant Betelgeuse takes on a strong orange tint as the brightest star on the upper left. Orion’s hot blue stars are numerous, with supergiant Rigel balancing Betelgeuse on the lower right, and Bellatrix at the upper right. Lined up in Orion’s belt are three stars all about 1,500 light-years away, born from the constellation’s well-studied interstellar clouds. Just below Orion’s belt is a bright but fuzzy patch that might also look familiar – the stellar nursery known as Orion’s Nebula. Finally, just barely visible to the unaided eye but quite striking here is Barnard’s Loop – a huge gaseous emission nebula surrounding Orion’s Belt and Nebula discovered over 100 years ago by the pioneering Orion photographer E. E. Barnard.

Hurry! You Can Catch a Ride to Jupiter with NASA

Well, at least your name can.  

One of the planet Jupiter’s largest and most intriguing moons is called Europa. Evidence hints that beneath its icy shell, Europa hides an ocean of liquid water – more water than all of Earth’s oceans combined. In 2024, our Europa Clipper robotic spacecraft sets sail to take a closer look…and when it launches, your name can physically be aboard! Here’s how: 

NASA’s Message in a Bottle campaign invites people around the world to sign their names to a poem written by the U.S. Poet Laureate, Ada Limón. The poem connects the two water worlds — Earth, yearning to reach out and understand what makes a world habitable, and Europa, waiting with secrets yet to be explored.

The poem will be engraved on Europa Clipper, along with participants' names that will be physically etched onto microchips mounted on the spacecraft. Together, the poem and names will travel 1.8 billion miles to the Jupiter system.

Signing up is easy! Just go to this site to sign your name to the poem and get on board. You can send your name en español, too. Envía tu nombre aquí.

The Europa Clipper launch window opens in October 2024, but don’t wait – everyone’s names need to be received this year so they can be loaded onto the spacecraft in time. Sign up by Dec. 31, 2023.

We hope you’ll be riding along with us! Follow the mission at europa.nasa.gov.
