We discuss the photometric performance and calibration of the Wide Field Planetary Camera
2 (WFPC2) on the Hubble Space Telescope (HST). The stability and accuracy of WFPC2 …

Respiratory surfaces are exposed to billions of particulates and pathogens daily. A protective
mucus barrier traps and eliminates them through mucociliary clearance (MCC) 1 , 2 . …

HH 30 in Taurus has been imaged with the Hubble Space T elescope WFPC2. The images
show in re—ected light a—ared disk with a radius of about 250 AU that obscures the protostar…

The WFPC2 was installed in the Hubble Space Telescope (HST) in 1993 December. Since
then, the instrument has been providing high-quality images. A significant amount of …

We present deep photometry obtained with the Hubble Space Telescope in a field in Baade's
window in the Galactic bulge. We derive a luminosity function down to I∼ 24.3, or V∼ 27.5…

Wide-field optical surveys have begun to uncover large samples of fast (t rise ≲ 5 d), luminous
(M peak < −18), blue transients. While commonly attributed to the breakout of a supernova …

We have observed SN 1987A with the optically corrected WFPC2 on the Hubble Space
Telescope both in emission lines and in the UV and optical continuum. The previously observed …

Long-duration gamma-ray bursts (GRBs) are powerful cosmic explosions, signaling the death
of massive stars. Among them, GRB 221009A is by far the brightest burst ever observed. …

Far-ultraviolet images of Jupiter from the Hubble Space Telescope Wide Field Planetary
Camera 2 reveal polar auroral emissions at 300 kilometer resolution and three times higher …

Dengue virus (DENV), a flavivirus of global importance, is transmitted to humans by mosquitoes.
In this study, we developed in vitro and in vivo models of saliva-mediated enhancement …
