Researchers design CubeSats with lasers to provide steady reference light for telescopes investigating distant planets.
ESO’s Director General and the Managing Director of the Cherenkov Telescope Array (CTA) Observatory have signed the agreement needed for CTA’s southern hemisphere array to be hosted near ESO’s Paranal Observatory in Chile. In addition, the Chilean Government and ESO have signed the agreement enabling ESO to host this new telescope within ESO’s Paranal Observatory site. This will allow the world's most ambitious gamma-ray observatory to access not only Chile’s pristine observing conditions, but also ESO’s state-of-the-art infrastructure, expertise, and facilities. ESO will operate the facility on behalf of the CTA Observatory and its Members.
Our newest planet-hunting telescope is up and running at the ESO’s Paranal Observatory in the Atacama Desert in Chile. SPECULOOS, which stands for Planets EClipsing ULtra-cOOl Stars, is actually four 1-meter telescopes working together. The first images from the ‘scopes are in, and though it hasn’t found any other Earths yet, the images are still impressive.
Located about 7500 light-years from Earth, in the constellation of Carina, lies a star-forming region known as the Carina Nebula. This dynamic, evolving cloud of interstellar gas and dust measures about 300 light-years in diameter and is one of the Milky Way’s largest star-forming regions. It is also an exercise in contrasts, consisting of bright regions of gas illuminated by intense stellar radiation and dark pillars of dust that obscure star formation.
The study of exoplanets has advanced by leaps and bounds in the past few decades. Between ground-based observatories and spacecraft like the Kepler mission, a total of 3,726 exoplanets have been confirmed in 2,792 systems, with 622 systems having more than one planet (as of Jan. 1st, 2018). And in the coming years, scientists expect that many more discoveries will be possible thanks to the deployment of next-generation missions.
Since it was launched in 2009, NASA’s Kepler mission has continued to make important exoplanet discoveries. Even after the failure of two reaction wheels, the space observatory has found new life in the form of its K2 mission. All told, this space observatory has detected 5,017 candidates and confirmed the existence of 2,494 exoplanets using the Transit Method during its past eight years in service.
In 1926, famed astronomer Edwin Hubble developed his morphological classification scheme for galaxies. This method divided galaxies into three basic groups – Elliptical, Spiral and Lenticular – based on their shapes. Since then, astronomers have devoted considerable time and effort in an attempt to determine how galaxies have evolved over the course of billions of years to become these shapes.
The construction of the world’s largest telescope has begun. At a ceremony at the European Southern Observatory’s (ESO) Paranal Observatory in Chile, officials gathered to celebrate the first stone of the European Extremely Large Telescope’s (E-ELT) long-awaited construction. Sophisticated telescope projects like the E-ELT take many years, so we can expect another similar ceremony sometime in 2021, when the E-ELT will see first light.
A powerful new array of radio telescopes is being deployed for the first time this week, as the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile joins a global network of antennas poised to make some of the highest resolution images that astronomers have ever obtained. The improved level of detail is equivalent to being able to count the stitches on a baseball from 8,000 miles away.
When astronomers point their telescopes up at the sky to see distant supernovae or quasars, they’re collecting light that’s traveled millions or even billions of light-years through space. Even huge and powerful energy sources in the cosmos are unimaginably tiny and faint when we view them from such a distance. In order to learn about galaxies as they were forming soon after the Big Bang, and about nearby but much smaller and fainter objects, astronomers need more powerful telescopes.
