During the Asymptotic Giant Branch (AGB) phase, the star undergoes mass loss, emitting a circumstellar shell of hydrogen gas. When this phase comes to an end, the star enters the PPN phase, where it is energized by a central star, causing it to emit strong infrared radiation and become a...
stars are normally born in stellar nurseries. Nurserys are nebulas of dust and clouds that are dormant until an event such as a supernova explosion starts the cloud to collapse and create the stars and planets. stars can form in pairs, known as binary stars or in larger groups. when ...
The principal force at work here is gravity, which causes the tenuous interstellar medium to condense into a nebula, and gravity that causes clumps inside the nebula to collapse down into stars. A spectacular Hubble image showing the huge "stellar nursery" in the 30 Doradus nebula. (Image cred...
Most years, I do you a solid and highlight just one stellar new Halloween picture book. This year, I couldn’t choose so you’re getting seven (sorry, not sorry). Actually, one of them—Oliver Jeffers’ There’s a Ghost in This House—you’ve seen before. It came out last year bu...

A celebration of beauty, “Louis Comfort Tiffany: Treasures from the Driehaus Collection” features more than 60 objects, spanning over 30 years of Tiffany’s prolific career. The exhibition showcases Tiffany’s innovative work in leaded and blown glass, including stellar examples of his famous win...
How Do Stars Form in Nebulas?Stars are born in clouds of gas and dust. One such stellar nursery is the Orion Nebula, an enormous cloud of gas and dust many light-years across. Turbulence from deep within these clouds creates high density regions called knots. ...
The U.S. isn't a stellar place for keeping a good ratio of work to the rest of your life, and other examples worldwide show various ways in which it could be better — or worse. If you're feeling overwhelmed and worried about the way your job is encroaching on the ...
Stock up! They can be frozen and used as needed. Another great holiday offering in stock now are both of our brittles—peanut and pecan. (Which is your favorite?) We think the brittles make great gifts and party treats, and the reviews of them have been stellar!
