TL;DR: The observations reveal that at least seven planets with sizes and masses similar to those of Earth revolve around TRAPPIST-1, and the six inner planets form a near-resonant chain, such that their orbital periods are near-ratios of small integers.

TL;DR: In this article, the spectral properties of the fullerene C_(60) in the reflection nebula NGC 7023 were confirmed by detecting a third emission feature at 7.04 ± 0.05 μm.

TL;DR: In this article, the spectral properties of neutral C$60$ in the interstellar medium were confirmed by detecting a third emission feature at 7.04 $pm$ 0.05 $m in the reflection nebula NGC 7023.

TL;DR: In this paper, an adaptive centroiding and repositioning method (Peak-Up) that uses the Spitzer Pointing Control Reference Sensor (PCRS) to repeatedly position a target to within 1 IRAC pixels of an area of minimal gain variation was proposed.

TL;DR: In this paper, the authors present an analysis of the most comprehensive NIR variability data set of Sagittarius A* to date: eight 24 hr epochs of continuous monitoring of Sgr A* at 4.5 μm with the IRAC instrument on the Spitzer Space Telescope, 93 epochs from 2.18 μm data from Naos Conica at the Very Large Telescope, and 30 epoch of 2.12 μm from the NIRC2 camera at the Keck Observatory, in total 94,929 measurements.
