More recent discoveries from the MK observatories:
"Astronomers detect dozens of new quasars and galaxies"
"A team of astronomers led by Yoshiki Matsuoka of the National Astronomical Observatory of Japan (NAOJ) has detected a treasure trove of new high-redshift quasars (or quasi-stellar objects) and luminous galaxies. The newly found objects could be very important for our understanding of the early universe."

There's actually more to come on this, as there has been recent news about detecting extremely distant quasars based on UKIRT data. I'll post about that later.
"Into the submillimeter—the early universe's formation"
Submillimeter galaxies are called that because they are really only visible at those wavelengths (in between infrared and radio wavelengths). They are very distant and full of dust which obscures optical light. These galaxies form stars at an amazing rate, several hundred times the rate the Milky way does for instance. The research involved both UKIRT and the JCMT on MK.
"These 52 galaxies were first identified by the Submillimeter Common-User Bolometer Array (SCUBA-2) in the UKIDSS Ultra Deep Survey."
The wording here is poor as SCUBA-2 is at the JCMT whereas UKIDSS was a survey carried out using the WFCAM instrument at UKIRT. What they mean is that JCMT followed up on these objects after they were first discovered by UKIRT.

"Recently discovered solar system could seed life between adjacent exoplanets"
UKIRT helped confirm the existence of some of the TRAPPIST-1 exoplanets. Now it seems that they are so close together, if life exists there it could easily transfer itself between the planets in a very short period of time.
"The researchers ran several simulations for TRAPPIST-1 and found that the process could occur over a period as short as 10 years. Most of the mass transferred between planets that would be large enough for life to endure irradiation during transfer and heat during re-entry would be ejected just above escape velocity, they concluded."
