It’s official: The Prince Couple are expecting a child

Kungahuset announced today: “Prince Carl Philip and Princess Sofia are delighted to announce that The Princess is expecting their second child. The birth is expected to take place in September 2017.”

“We are happy to announce that we are expecting a child, a sibling to Prince Alexander. We are looking forward to welcoming a new little member to our family,” says Prince Carl Philip and Princess Sofia.

No changes in the schedule of The Prince Couple’s public engagements are planned during the spring and summer of 2017.

Congrats to the happy family of soon to be 4. Alexander will be a great big brother.

Astronomy From 45,000 Feet

What is the Stratospheric Observatory for Infrared Astronomy, or SOFIA, up to?

SOFIA, the Stratospheric Observatory for Infrared Astronomy, as our flying telescope is called, is a Boeing 747SP aircraft that carries a 2.5-meter telescope to altitudes as high as 45,000 feet. Researchers use SOFIA to study the solar system and beyond using infrared light. This type of light does not reach the ground, but does reach the altitudes where SOFIA flies.

 Recently, we used SOFIA to study water on Venus, hoping to learn more about how that planet lost its oceans. Our researchers used a powerful instrument on SOFIA, called a spectrograph, to detect water in its normal form and “heavy water,” which has an extra neutron. The heavy water takes longer to evaporate and builds up over time. By measuring how much heavy water is on Venus’ surface now, our team will be able to estimate how much water Venus had when the planet formed.

We are also using SOFIA to create a detailed map of the Whirlpool Galaxy by making multiple observations of the galaxy. This map will help us understand how stars form from clouds in that galaxy. In particular, it will help us to know if the spiral arms in the galaxy trigger clouds to collapse into stars, or if the arms just show up where stars have already formed.

We can also use SOFIA to study methane on Mars. The Curiosity rover has detected methane on the surface of Mars. But the total amount of methane on Mars is unknown and evidence so far indicates that its levels change significantly over time and location. We are using SOFIA to search for evidence of this gas by mapping the Red Planet with an instrument specially tuned to sniff out methane.

The plumes, illustrated in the artist’s concept above, were previously seen in images as extensions from the edge of the moon. Next our team will use SOFIA to study Jupiter’s icy moon Europa, searching for evidence of possible water plumes detected by the Hubble Space Telescope. The plumes were previously seen in images as extensions from the edge of the moon. Using SOFIA, we will search for water and determine if the plumes are eruptions of water from the surface. If the plumes are coming from the surface, they may be erupting through cracks in the ice that covers Europa’s oceans. Members of our SOFIA team recently discussed studying Europa on the NASA in Silicon Valley Podcast.

This is the view of Jupiter and its moons taken with SOFIA’s visible light guide camera that is used to position the telescope.
