[/caption] Wow, what a gorgeous new image from the Herschel telescope – and what makes this especially stunning is that we've never seen these stars before! And these stars in the Rosette Nebula are huge, as each one is up to ten times the mass of our Sun. "High-mass star-forming regions are rare and further away than low-mass ones," said Frédérique Motte, from the Laboratoire AIM Paris-Saclay, France. "So astronomers have had to wait for a space telescope like Herschel to reveal them."

The Rosette Nebula is about 5,000 light years from Earth. Each color shown in the image represents a different temperature of dust, from –263 C (only 10C above absolute zero) in the red emission to –233 C in the blue.

The bright smudges are dusty cocoons hiding massive protostars, which will eventually become equally large stars, still about ten times the mass of the Sun. The small spots near the center and in the redder regions of the image are lower mass protostars, similar in mass to the Sun.

The image shows about half of the nebula and most of the Rosette cloud. The Herschel space observatory is able to peer through the dust and gas to see what is invisible to our eyes. The image was created using observations from Herschel's Photoconductor Array Camera and Spectrometer (PACS) and the Spectral and Photometric Imaging Receiver (SPIRE).

We can look forward to learning about the first scientific results from Herschel, presented by Dr. Motte, at a symposium hosted on May 4-7, 2010 in the Netherlands by the ESA, the ESLAB symposium.

She is currently retired from daily writing, but worked at Universe Today for 20 years as a writer and editor. She also contributed articles to The Planetary Society, Ad Astra (National Space Society), New Scientist and many other online outlets.

Her 2019 book, "Eight Years to the Moon: The History of the Apollo Missions,” shares the untold stories of engineers and scientists who worked behind the scenes to make the Apollo program so successful, despite the daunting odds against it. Her first book “Incredible Stories From Space: A Behind-the-Scenes Look at the Missions Changing Our View of the Cosmos” (2016) tells the stories of 37 scientists and engineers that work on several current NASA robotic missions to explore the solar system and beyond.

Nancy is also a NASA/JPL Solar System Ambassador, and through this program, she has the opportunity to share her passion of space and astronomy with children and adults through presentations and programs. Nancy's personal website is nancyatkinson.com
