In August 2006 a new planetary transit was discovered from data from the TrES network. The discovery was confirmed using radial velocity curves obtained with the Keck and characterised with light curves in different filters obtained using two telescopes at the Observatorio del Teide: "IAC80" and "TELAST" (the first result of scientific interest obtained from the latter). The planet discovered, TrES-2, is more massive and somewhat larger than its quasi-homonym TrES-1 (the first exoplanet discovered using the transit method), and follows the expected patterns for this type of object. Its main importance is that it is the first object discovered in the area of observation of the future Kepler satellite, which will be able to track it in a degree of detail never before achieved.

    Evolution of stellar magnetic activity: the Sun has similar magnetic activity as its pairs
    It’s been decades since the need to study other stars to understand the past, present and future of the Sun was realized. One important aspect that has been investigated is the magnetic activity of stars for which we cannot fully grasp the mechanisms involved. Indeed, the origin of stellar magnetic cycles or the dependence of the magnetic activity on the stellar properties are not completely understood. This knowledge improves not only our understanding of the physics involved in stellar evolution but also affects the study of the Sun to better predict high-energy events and the better

    Exploring the atmosphere of GJ 1132 b with CRIRES+
    The rocky planet GJ 1132 b, with Earth-like mass and radius, is a prime candidate for atmospheric studies. Previous observations with Hubble and JWST yielded conflicting results about its atmosphere. This study used three transit observations with the CRIRES+ instrument to search for He i, HCN, CH₄, and H₂O in GJ 1132 b's atmosphere. No clear atmospheric signals were detected, but upper limits for CH₄, HCN, and H₂O were established. The results suggest that if GJ 1132 b has an atmosphere, it is not dominated by hydrogen. The work highlights the challenges of detecting high molecular weight

    A new way to measure the distance to NGC1052-DF2
    O ne of the key challenges in astronomy is to measure accurate distances to celestial objects. Knowing distances is crucial since it allows us to measure physical properties such as size, mass and luminosity. Since we can’t go out and use a tape-measure, a range of different approaches have been developed. Many of these approaches rely on using “standard candles”. Standard candles are objects (for example stars or supernovae) for which we know their intrinsic ”true” brightness. Once we know this, then their observed brightness compared to their intrinsic brightness gives us a distance to the
