New Frontiers: U.S. Space Force, Zenno, and SpaceX Propel the Next Era of Space Innovation

The US Space Force is making headlines by awarding contracts to Viasat and Intelsat for new anti-jam communication satellites. These are part of a program to develop a jam-resistant satellite communication fleet, and it’s a pretty big investment—we’re talking hundreds of millions of dollars.On a global scale, there's some exciting news from Zenno Astronautics—they've become the first company to operate a superconducting product in space, which is a huge leap for space infrastructure technology.And if we zoom in a bit, there’s also a lot of buzz around SpaceX and its recent IPO. The company's shares have been soaring, and it’s causing a lot of excitement in the market.It’s definitely an exciting time in space industry!

Ultrared, dusty star-forming galaxies in the early universe

Star formation takes place within natal clouds of dust and gas that absorb much of the emitted ultraviolet and optical radiation but which also block these regions from optical view. In recent decades, however, infrared space-based observatories like Herschel and Spitzer have revolutionized our understanding of obscured star formation in dusty galaxies because infrared light can penetrate the dust clouds to reveal the stars being formed. Herschel and Spitzer have discovered large numbers of very dusty, very red star-forming galaxies that are immensely luminous in the infrared (exceeding one trillion solar-luminosities) yet are not seen at shorter wavelengths. In fact, these dusty galaxies are responsible for most of the infrared background light in the cosmos. Some of these objects display the most extreme kinds of starbursts known, with star formation rates exceeding a thousand per year, but which are also exceedingly rare with on average only one of them in a volume of a few hundred thousand million cubic light-years.
