The Hubble Space Telescope is a beloved scientific institution, but at more than 20 years old it’s getting rather long in the tooth. That’s why NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA) are joining forces to create the James Webb Space Telescope, a cutting-edge astronomy instrument that is set to launch later this year.

The instruments on board James Webb will enable science discoveries beyond anything possible right now, such as looking at exoplanets to see if they have atmospheres and whether any might be like Earth.

But exoplanet atmospheres aren’t the only topic that Webb will be researching. This week, NASA officials have announced the roster of scientific programs which the telescope will study in its first year. This includes programs to research how stars are formed, research into the climate and composition of bodies like planets and comets within our own solar system, and even programs to study the formation of the universe itself by looking for the earliest galaxies.

“The initial year of Webb’s observations will provide the first opportunity for a diverse range of scientists around the world to observe particular targets with NASA’s next great space observatory,” said Dr. Thomas Zurbuchen, Associate Administrator for the Science Mission Directorate at NASA in a statement. “The amazing science that will be shared with the global community will be audacious and profound.”

All of these programs will be a part of Cycle 1, which is the name for the first year of the telescope’s science operations. In total 266 proposals were selected from a highly competitive pool of thousands, as many more researchers would like time on the telescope than is available. The committee in charge of the selection had to whittle down the proposals to the most scientifically valuable, and they ended up awarding 6,000 hours of time on the telescope to the various projects.

“We are opening the infrared treasure chest, and surprises are guaranteed,” said Dr. John C. Mather, Senior Project Scientist for the Webb mission and Senior Astrophysicist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “How did the universe make galaxies, stars, black holes, and planets, and our own very special little Earth? I don’t know yet, but we are getting closer every day.”

Get out the scrapers: Euclid space telescope is getting deiced
Artist's impression of the Euclid mission in space.

If you thought it was annoying to deice your car in the winter, then spare a thought for the engineers whose job it is to deice telescopes in space. The European Space Agency's (ESA) Euclid space telescope is currently undergoing a deicing procedure to remove a few layers of water ice that are less than a nanometer thick but enough to impede the telescope's highly accurate measurements.

The expansion rate of the universe still has scientists baffled
This image of NGC 5468, a galaxy located about 130 million light-years from Earth, combines data from the Hubble and James Webb space telescopes. This is the most distant galaxy in which Hubble has identified Cepheid variable stars. These are important milepost markers for measuring the expansion rate of the Universe. The distance calculated from Cepheids has been cross-correlated with a Type Ia supernova in the galaxy. Type Ia supernovae are so bright they are used to measure cosmic distances far beyond the range of the Cepheids, extending measurements of the Universe’s expansion rate deeper into space.

The question of how fast the universe is expanding continues to confound scientists. Although it might seem like a fairly straightforward issue, the reality is that it has been perplexing the best minds in physics and astronomy for decades -- and new research using the James Webb Space Telescope and the Hubble Space Telescope doesn't make the answer any clearer.

Scientists know that the universe is expanding over time, but what they can't agree on is the rate at which this is happening -- called the Hubble constant. There are two main methods used to estimate this constant: one that looks at how fast distant galaxies are moving away from us, and one that looks at leftover energy from the Big Bang called the cosmic microwave background. The trouble is, these two methods give different results.
