In the past of the Galaxy Zoo, volunteers pointed out two galaxy mergers that have a surprisingly similar shape with penguins: First dailyzoo-post Second dailyzoo-post I think the similar pattern is no coincidence: There are two galaxies merging with each other. One galaxy is an elliptical galaxy without triggered star-formation and another galaxy with mainly… Continue reading Penguin Galaxies
In the “about” page of the Milky Way Project you can read in the describtion of bubbles: Bubbles are interesting places — they mark the locations where radiation from newly formed massive stars is impacting on the surrounding cloud material. But how can you find those stars if one bubble has sometimes hundreds or thousands… Continue reading How to find massive stars…with bubbles!
A reflection nebula is a cloud of interstellar dust that scatters the light of one star or many stars. The light of a reflection nebula does have similar spectra like the light it scatters. Because the stars are often blue, many reflection nebulae are blue and they are different from emission nebula, which have different… Continue reading Reflection Nebulae, Bubbles and B-Type Stars
The Mid-Infrared is good to study hot gas and dust in close galaxies. The Spitzer Space Telescope did already study the gas in close galaxies, like the spiral Andromeda galaxy or the dwarf galaxies Large Magellanic Cloud (LMC) and Small Magellanic Cloud (SMC). Beside these very close galaxies, spitzer did image more distant galaxies, as… Continue reading Galaxies in the Mid-Infrared
In the Milky Way Project we look for bright sturctures, like Infrared-bubbles or bowshocks. Infrared Dark Clouds are something the volunteers are adviced to ignore: “If you see dark splotches in an image, they might be part of a ‘dark cloud’ of gas and dust. You need not classify these objects!” Infrared Dark Clouds (IRDCs)… Continue reading Coffee in Space
I did post about Tadpoles in general and about proplyds and proplyd-like objects in detail. Here I want to write about the different pattern of Tadpoles and their connection to different regions. The main pattern that we can see in the Milky Way are: Cometary Globule, Evaporating Gas Globule, Pillar and Proplyd(-like object). Cometary Globule… Continue reading More about Tadpoles
In a previous post I did mention proplyds we found in the Milky Way Project. Here I want to tell the story about the discovery of proplyds and proplyd-like objects in the MWP phase 3, called phoenix. Everything began with the Subject 2871496 and the discussion I started: @Melina_t: I don’t know what these two… Continue reading Proplyds and proplyd-like objects
